Yes, I think there's a lot you can control in your life that will bring you happiness. I have no spiritual hunger that I'm aware... nothing that a bacon sarnie couldn't cure at any rate.
Im very happy in my life thanks, I yearn for very little!! Being an atheist is so pleasing and reassuring, we don't need to be afraid of any fairytale gods!!
Of course my everyday happiness is up to me......it's how I deal with life that determines my state of happiness or otherwise.
I can, however, think of one or two things.......dependent on other people.. that can make me very, very happy. And they are most definitely not spiritual.
