It's very counter intuitive, but selfishness is actually a sign of depression.
I can say from personal experience that this is true. In a way, no one can save themself. One can only be saved in saving another, that's what I'm beginning to believe.
I'm still having trouble getting past the selfish part. :x
But all that aside, Gatto worded it perfectly for me. Like really, those are the kind of things that make me happy. Driving with the window down so the wind blows past me, seeing the leaves turn, that smell that comes with autumn, those are the things that make sticking around this place worth it.
