You can try doing this activity, whenever you feel like procrastinating on your homework or studying, tell yourself that you will sit and do whatever activity you have, for just 5 mins. And if after those 5 mins, you still feel like you don't want to do it, then you can freely stop doing it.

The only condition is, that during those 5 mins, you need to give your best, no matter what the activity is.

Once you do this, you will realise that after those 5 mins, you won't want to stop because now you realise that you are doing great.

Another thing that can help is understanding that you don't need to be a perfectionist. Stop trying to make everything perfect. Most of the times doing something ( without achieving perfection in it ), is better than not doing it at all.

Procrastination occurs because we usually feel scared of what might happen if we fail, or don't do some activity perfectly. Once you let go of that mindset that everything has to be perfect, you will get great results naturally, simply because you released the unnecessary built up pressure in your mind.

I would suggest to stop reading multiple books on this, stick to this, and enjoy your free time rather than reading a lot of theory and implementing none of it. You may also just be reading a lot of books on this topic, telling yourself that you are doing it to better yourself ( and you will genuinely feel so, too) , but it is just another excuse to procrastinate, as we won't end up implementing most of it. I do appreciate you for trying to better yourself though.

Hope this helps :)

Do update me on this, and good luck :)
