1. Being Too Strict or Too Lenient
It's said that too much of anything is bad, so being a leader who is either too strict or too lenient is not ideal. A wise leader knows when it's time to "loosen up" or "tighten up". If you are too strict, employees may perceive you as oppressive and authoritarian; on the other hand, if you are too lenient, you risk coming across as weak. Therefore, always try to assess how your employees view your leadership style and adjust accordingly.

2. Being Too Cold, Distant, or Arrogant
Leaders who are overly cold, distant, or arrogant only drive employees away. A leader must make an effort to show their team that they are there for them, working for their benefit. Only then will employees be motivated to follow, contribute their energy, and apply their intellect to the tasks under your leadership.

3. Doing Too Much and Leading Too Little
Some leaders tend to take on too many tasks themselves, lacking trust in their subordinates and refusing to delegate. However, this isn't the responsibility of a leader. A leader should be capable of showing their team that they are willing to do whatever it takes to support them, while still remembering what their true responsibilities are. A successful leader is not someone who can outperform their employees ten times over, but someone who can inspire ten employees to work for them. Although doing things yourself may seem easier, a leader will fail if they do all the work themselves.

4. Creating an Impression of Favoritism
In reality, each of us can show favoritism at times, and leaders are no exception. Employees who are particularly vocal and outgoing often receive more attention in the workplace. Workers expect fair treatment and to be free from favoritism from their leaders. Therefore, leaders must be extremely cautious to meet these expectations.

5. Betraying trust
Earning someone's trust is never an easy task. Once that trust is lost, regaining it becomes nearly impossible. Leaders should never make promises they cannot keep. As a leader, it is essential to think before speaking. If you tell your team you will do something, you must follow through to maintain their trust.

6. Harboring Resentment and Hatred
Intense debates can lead leaders to harbor resentment and hatred toward their employees. If a leader persists in holding onto these negative feelings, it will only damage their ability to lead. This is because employees will feel that their mistakes and shortcomings will never truly be forgiven, and that the leader will never forget, which will inevitably result in reduced work efficiency.

7. Micromanagement
Leaders must always remember that there are numerous ways to get the job done. They should not interrogate, analyze, criticize, or guess the actions of their employees. This approach may lead employees to think, "Why doesn't the leader just do it themselves to get it done faster?" Some leaders hold significant positions but fail to bring positive outcomes for everyone. They use their authority to force employees to do what they want without consulting their input. For these leaders, the term "effective leadership" is a distant concept.

8. Lack of Strategic Thinking Ability
Leaders need to have strategic thinking skills because if employees want to understand the strategic plans they are contributing to, and the leader is unable to communicate these plans, it will demotivate the staff. This lack of communication prevents employees from realizing the importance of their contributions.

9. Not being open to adapting to individuals with different attitudes
Leaders must be ready to adapt to people with different attitudes. You must accept the reality that each person in your team has their own thoughts, reacts, or works in different ways, and you need to work with people like that. Therefore, a leader must make an effort to understand these differences within their team, so that employees will want to stay and work for you.

10. Disregarding the organization’s policies and procedures
Another thing a leader must avoid is disregarding the organization's policies and procedures. The attitude and behavior of employees reflect the attitude and behavior of the leader. A leader should not show opposition or disregard for collective decisions, as well as policies and procedures, in front of employees. Complaining in front of staff is unprofessional; instead, leaders should find the right person to address the issue.

11. Delaying action when immediate action is required
Delaying action at the wrong moment is one of the biggest obstacles to effective leadership. None of us can avoid conflicts. Avoiding them in hopes that the issue will resolve itself only makes the problem worse over time. Therefore, in order to lead effectively, a leader must take action as soon as they recognize it is necessary to do so.

12. Being quick to give advice
As a leader, you should avoid offering advice. If employees follow your advice and the results don’t meet expectations, who will they blame? Your leadership role already faces enough challenges, so there’s no need to create unnecessary problems. Instead, encourage and praise your employees, correct their mistakes, but refrain from giving advice.

13. Being overly ambitious
To be a great leader, one should avoid excessive ambition. It’s not right to advance at the expense of others for personal gain. This behavior causes employees to perceive their leader negatively. A good leader knows that there are many ways to achieve success, and that success should be acknowledged and supported by others.

14. Settling for what has been achieved
A leader should never be satisfied with their current achievements and should always push their employees to perform even more effectively, expecting more from them. Take time to identify areas for improvement and focus on developing them further.

15. Abusing one’s position
Many leaders have misused their authority and position to pressure their employees. When they become leaders, they have the potential to either grow or inflate themselves. Normal growth is beneficial, but inflating oneself only leads to an inevitable collapse. If your power and position are abused, they too will eventually burst under the strain.

16. Failure in Effective Workforce Allocation
In certain organizations, leaders often assign tasks to more competent employees, while those with limited abilities face fewer challenges. The result is that the highly capable employees become overburdened, leading to a decline in their work efficiency. Great leaders understand the importance of their employees, especially those with skills. As an organization grows, the leader must build a team of capable workers with a strong work ethic and the necessary skills. It's a failure for leadership if employees simply show up, spend their time idly chatting, and leave at the end of the day (a situation commonly seen in public institutions). Moreover, a major failure for leaders is their inability to use human resources effectively.

17. Lack of Discipline
As a "leader", you must set an example in every aspect, both in your words and actions. Subordinates will pay close attention to this, and through personal observation, employees can determine which behaviors are truly acceptable within the organization. When a leader arrives late, takes unapproved time off, or has a disorganized desk, it doesn't go unnoticed by the staff. Therefore, in order for a leader to earn the respect and compliance of their team, they must elevate their own sense of discipline.

18. Focusing too much on personal gain and neglecting the value of talented individuals
As a leader, you should not solely prioritize your own interests while disregarding the collective well-being. Decisions that benefit you personally should be made swiftly, while those that do not may be delayed, postponed, or complicated. The employees are the right-hand support of leaders. When employees perform their tasks well, the leaders can succeed in their duties. If tasks are not completed successfully, part of the reason may be due to poor management skills. A leader must recognize and utilize talent—individuals who can fill your gaps. Moreover, special recognition and incentives for skilled individuals should be in place, motivating them to perform better and improving the team's overall efficiency. Employees may become discouraged if their hard work goes unnoticed or unappreciated. Timely recognition and reward for their contributions will foster their loyalty and boost their sense of responsibility. As for employees who make mistakes, avoid publicly criticizing them or using meetings to expose their errors. Instead, handle it discreetly and constructively, unless you intend to dismiss them.

19. Poor judgment
A good leader must possess the ability to make quick and accurate judgments. However, not all leaders are able to do this. Some leaders lose their ability to guide effectively, often making poor decisions, speaking, and acting impulsively. As a result, they make choices without considering the actual situation, allowing emotions to override actions. Therefore, before making any decision, a leader must ask themselves three questions: First, is this beneficial for my organization? Second, is this good for my employees? Third, is this advantageous for my future? If the answer to all three questions is 'no,' then the decision should either be avoided or further research should be done before proceeding.

20. Lack of sensitivity to the needs of others
As a leader, it is important to be attuned to the needs of your employees. For example, if an employee requests time off for personal reasons, instead of questioning why they need the time off or if they want any assistance, you might react with dissatisfaction. You might assume they are taking advantage of your leniency, or question their work performance, especially if the company is busy. Worse yet, you may respond by saying: 'Why are you taking time off when we're so busy, and without any prior planning? If you need time off, just take it. When you're back, let me know if you still want to work.' This kind of reaction could lead to them submitting a resignation immediately after their leave or even right after the conversation.
