I want (You) to have positive outlook on your future because You are the one who is shaping it, have some more faith in yourself, you are the only one who can change something and everything in your life, so don't be a lazy one.
If you are at this time not enjoying yourself it's okay, look for the things you enjoy, yes the little things matter too... if you are doing it for the long run, like collage degree, it's really worth it!
Also eat and drink well, you wouldn't imagine how big of a impact balanced diet has only your mind.
