You know what I do when I'm sad?
I say "F--- it I'm not going let this(whatever is bothering me) have control over my emotions.", hop into the Jaguar or Mercedes(soon to be a Bentley that I'm getting for 30th b-day present) go for a spin, put on some Metallica and think and realize "I have one hella cool life. What! I'm doing it, son! This here thing that got me sad is nothing. It's nothing. I got this here because I'ma boss."
(car nut here. Cars always cheer me up. While many people look online at a car and sigh wishing they can get a car that they are looking at, I look at a car online, find a way to get it, see it in person and then go buy it for myself.)
