You're not the only one who can't revise. I always seem to find an excuse for avoiding it - lately it has been watching movies that are on the TV. Then in the night when it's all quiet and I'm about to go to bed I sit and think 'exams are coming up soon, I need to pull myself together and get loads of revision done tomorrow to make up for the lack of it so far!' feeling guilty, but then the next day comes... and I never do the amount of work I say I'll do. Usually I avoid it again by eating breakfast, then relaxing for a bit, and before I know it half the day has gone by again...
