“Where do you find happiness? Is it out there somewhere waiting to be discovered? Under a rock? Out in the woods? Buried in the desert? Where do you find it? You don’t find happiness. You make it. You put forth effort. You work for it. You take on responsibility. You put yourself out there; you take risk to achieve a worthy goal. And in that pursuit, if you pay attention, if you look around, you will find happiness.”
