If your life sucks, do something about it. But even if you choose not to, quit bitching about it. The secret to happiness is not about getting what you want. The secret to happiness is knowing that no matter what you do, there will always be pain and suffering. The rich suffer and the poor suffer. The talented suffer and so do those to have none. Guys who get girls bitch, guys who don't get girls bitch.
Knowing that you'll always have something to whine about and choosing to enjoy life instead, that's the secret to happiness.
