A*/A students how do you motivate yourself? Watch
It helps if you have something to look forward to from success i.e. a new life at University and the new opportunities from starting something new.
Set your mind to it, write what you plan to revise the day before, write out every day what went well and go for a goal-based approach where you're ticking things off as you're doing stuff.
Set a morning routine, listen to Motiversity and to quote Jason Capital - just keep ****n going!
Good Luck & that's enough serious writing for the week haha
