Back on topic, sort of.
No matter career you ultimately settle upon, you will need a good work ethic, a drive to get things done and not wait until the last minute and risk not being able to complete your work. (Hint,hint). And the best way to do that, as with anything, is practice. And I think your schoolwork would be the perfect opportunity.
Get crackin' on those books and stop putting off assignments. Being cramped for time has a tendency of producing shoddy work. Get crackin' now and it will be easier later. Good luck.
