What's the Key to Your Happiness?

Question:  What is the key to your happiness?

My Reply:
Honestly? Jesus Christ is the key to my happiness.
Don't get me wrong, everything's not always happiness, obviously...heck, if anything, life's sometimes harder with people hating me for my faith, the persecutions, criticisms from non-believers, etc..  But even when things have got me down, I know I'm not alone in this, and that I can turn to Jesus anytime for help.
