1. Take Breaks
Contrary to the previous advice, avoid playing the guitar for extended hours right from the start. If your muscles start to feel fatigued and your fingertips ache, it's time to rest and relax.
You can still learn a lot by listening to music, and overexerting yourself while practicing can strain your tendons and ligaments.

2. Avoid Gripping the Neck Too Tightly
When you're just starting out with guitar, pressing the strings onto the fretboard to produce sound can seem tough, and you'll likely feel pain in both your fingertips and wrists. To ease the discomfort, you may instinctively want to place your thumb higher up on the neck, unknowingly causing your fingers to press the strings with more of the palm than the tips.
The correct technique is to keep your thumb positioned at the back of the neck, ideally in the middle of the neck's rear. This encourages you to use the tips of your fingers for pressing the strings, which improves both the quality and accuracy of your playing, ensuring that other strings don't accidentally mute. The challenge is that it may feel awkward or difficult at first, especially if your wrist is still weak. But stick with this technique and you'll soon realize the huge benefits. Remember: thumb behind the neck.

3. Practice Playing Guitar While Standing
If you're ready to learn guitar, one day you'll find yourself playing standing up in front of a group. Playing guitar while standing is quite different from sitting. When seated, you can easily lean forward to see what your left hand is doing. But standing changes everything.
Try it once to understand what I mean. You'll notice it's hard to see your fingers. So my advice is to get yourself a good quality guitar strap and adjust it properly. Note: don't make the strap so long that the guitar hangs down to your knees. It may look cool, but you won’t be able to play properly. And remember to practice while standing regularly.

4. Practice Guitar Every Day
Nothing beats picking up your guitar every day and practicing the piece you're currently working on, even if it's just 15 minutes a day when you're busy with other tasks. Good technique comes from your brain and fingers memorizing how to create great sound, especially with challenging finger positions.
Try to set aside a fixed time each day and build a guitar-playing habit. This will help toughen your fingers quickly and make playing less painful in the long run.
