Don't sweat the small stuff.

It wasn't until recently that I truly understood the meaning of the above phrase. It's so simple, and so true. Don't get mad over stupid little things. Something small will only turn into something big if you let it happen. Stop wasting time being angry/disappointed/pissed over something small, because the other person just doesn't care, and in the end, you're the only one who will suffer. (And even if it really is big, make it small, because they still won't care.) It's so simple! I'm still trying to get over this realization. So from now on, I'm not going to get mad. That doesn't mean I don't care at all...just to a lesser extent.
