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.
And remember, you’re at university. Take advantage! Talk to your tutors, use the library, join a study group, etc. Just don’t put off your work and don’t rush – it’s all going to be okay.
Now it’s time to figure out what you actually want to eat, whether you need some juicy carbs to give you that pure energy, or something sweet to pick you up, or a salad to feel like you’ve conquered life.
