Chill out.

Sometimes, we need to take the backseat in life and just relax. I mean, yes, do what you need to do (in my case, a million assignments and the constant intake of chocolate-filled substances), but apart from that, don't bother too much. If you do, it's only going to lead to you obsessing over things that needn't be obsessed about. Let's say I've been there, done that. Maybe I'm still there, knowing me. But if there's one thing I've learnt, it's that this constant obsession about insignificant things that can very easily be brushed off the table of your thoughts, is simply not worth it.
Trust me, I know. Channel your energy into things more worthwhile, things that will actually change something about you, about the world, about your life.
Ah, if only I took my own advice.
