i need advice how to stop procrastination

1. Don't listen to music at all
2. Turn your phone off
3. Exit mangago and return in like 8 hours of studying or how ever long ya wanna study for
4. Study
5. If you can't concentrate while studying, fidget with something.

Fidgetting ideas:
* Throwing a small object up or down (e.g. pen/ rubber)
* Stress ball (if you don't have one, use a big ball of blue tack)
* No, fidget spinners do not help you to fidget and concentrate at the same time
* Get a fidget cube
