How to curb the cynical, sarcastic pessimist inside me
It made me
apathetic 
"enlightening."
How I did it: I didn't do it. I realized on my journey that not all people have good tendencies and that the cynical sarcastic pessimist asshole that i am is simply my personality and its something i'll have to accept.
I'll never be completely trusting of people, and i've always had a dry sarcastic sense of humor and people love me for it. being a cynic causes you to foresee problems that dreamers wouldn't see. people come to you for insight because you can see both sides of an issue. you just have to know when to turn off the cynical pessimist jerk and let your sweet side show.
