For GPA
Damn it!
When you got something, you got something to lose. I got a GPA of 3.93, so I got it to lose. It's annoying, the afraid of losing. To preserve it, I just called a teacher to beg him for a higher score, I felt ashamed but forced.
There are nothing ever built to last, when you're not afraid of losing everything, you own everything.
Think about the day you'll die, will you chase after these things? Life is short, you can't fall in love with everything, when you love one, go and dig in.
Life should be devoted to things you value, anything else, if not must, can be omitted. University is the place we start to independently treat our life. Life is a journey of finding things you love, so it's the first principle apart from living, you should consider. If you won't die because of starvation, you should use all of your time do things you like, or finding things you like.
