What is it called when a person doesn't believe in any kind of god, doesn't have a religion..?

..and isn’t interested in finding one? (since I find that “god” thing ridiculous)

I know the term “atheist” but I don’t use it to describe myself, mostly because of a few “atheists” I’ve met, and nooo..
So, here’s what I say: I believe in myself, and in what I can do and get away with.
Also, I believe in the power of love, the power of music, and passion.
And in the people I love.

(I see the word “believe”, but no god there. How’s it called?)
