My first tip would be to start tracking your spending. Yes, it’s boring, but better that than be stuck with no money for most of the term waiting for the next finance injection.
Most importantly, plan time to relax. If you don’t allow yourself some down time you’ll just end up dropping everything. The brilliant thing about planning time to relax is it removes any form of guilt. The voice in your head that says “you need to work” will not have any power anymore. Because this is your time to relax, you need to relax, not work.
