Just a correlation? Or a cause-and-effect situation?

I've come to conclude that even though I'm bored with my life but generally happy and keeping to myself, this is better for my grades and for trying to do well in school. In my life, when I have been outrageous, super involved with something that gives me great personal satisfaction, super social, and not always happy because I'm always in a lot of drama, I do really poorly in school. Just a few more years and I can go back to being that part of me.
