Atheists: Since you don't use religion to make you "good", What's your alternative?

I don't really make a point of going around being good; I just live my life and have morals. I spend time with my kids as much as possible because I think that is important; I try to be polite and kind to everyone, especially those who are rude and unkind, because they probably have things in their life that are negative and they could use some niceness directed toward them. I just do things I enjoy and be nice and kind to those people I come in contact with, and don't do bad things. That pretty much sums it up; it's pretty easy, uncomplicated, and fulfilling.
