Why Do I Procrastinate So Much?!

Why did you have this vision? Why did you say that day "I'm definitely going to revise!"? Are you determined to achieve? Or were you just saying that as something to brush over, something to give you an excuse to relax beforehand... "I'm so gonna start revision tomorrow, so I'll just chill tonight"

You must have had some drive or motivation, remind yourself what it was. Why do you want to revise? Why do you want good grades in these mock exams? If you can't answer that second question, then why are you studying those subjects?

If something is distracting you, just immediately remove the stimulus.
Don't do any of that 'use it as an incentive' or 'reduce the amount of time on it', just completely get rid of it. Laptop? Shut it down and hide it. Phone? Change the pin. TV? Stay in your room. Access it only at the very end of your revision. Because at that point, your brain is fried and tired and has barely got any energy left. It's better to waste that remaining energy on Facebook and Youtube than to use your fresh energy in the morning and afternoon.

If nothing works, you're just gonna have to muster up the determination and face the realisation that this is ****ing important, sit down with your notes, open it and say to yourself that you want to do this, you like doing this, and life isn't ****ing games anymore.
