I had a few friends ask me what my resolutions for 2012 were going to be. Seeing what other friends had been saying about theirs, they seemed much simpler this year: family, work, success, etc. So when I thought about mine, my simple responce is "optimism".
I believe I've gone down this path numerous times, preaching the good gospel of how happiness cures your ailments, ad nauseum. They are very easy words to say, but so hard to actually trust. There was a point in my life where I considered happiness to be a fundemental part of my life. Everyone knew me as the happy guy, funny, kind, big hearted, etc... at least for a while. Then they'd find me to be a liar, or lacking follow through, or being nosey with gossip and inconsideration. It was a serious rock-bottom reality check to realize that I wasn't nearly as morally sound as I pretended to be.
Years later, through hard work and no work at aall, the outgoing and funny guy has all but vanished, replaced with waves of confident men, sad men, angry men, defeated men, happy men, quiet men, loud men, honest men... the list goes on, but the point is that when I stopped having faith in the happiness, in a way, I gave up hope for fixing everything else, and I didn't even realize it at the time.
Happiness isn't that complicated, as long as you're not afraid to experience the other side of that for what it is, and you're thankful for the experience. Fear, anger, sadness... they are feelings equal in worth to happiness, and when you allow yourself to cry, to yell, or run, you're truly unlocking the door for happiness to be there with you.
Don't be afraid to be afraid.
