Henry chuckled again, followed by a relieved sigh. "Dean, if there's one thing I've learned from this experience, it's that happiness isn't something that just happens." His eyes focused on the clouds drifting by as he spoke. "Happiness is something you have to work for. Sometimes sweat and bleed for. If you don't actively try to be happy, then even the best things life has to offer will only keep you happy for a few minutes." He glanced back at Dean now. "I can't say that I'm happy yet, and I doubt it'll happen at the drop of a hat. But I'm going to try and be happy, so that when something does come along, I can actually be happy."
