There are two basic motivating forces: fear and love.
I'm not motivated by money and I never really have been.
Money is important, but it's not the only driving factor for me.
There's something about trying to figure out why someone is doing something that on the outside is horrible - what drives them to do that? What could drive any human being to that kind of behaviour?
I think the scientific goals and the technical challenges were the two things that equally motivated me.
If money was my only motivation, I would organize myself differently.
Competition doesn't drive me. It's not to say that competition is bad, it's not to say that competitive games are bad because I love that those that exist, but it's not my thing.
Technology is similarly just a catalyst at times for fundamental forces already present.
There is no force more potent in the modern world than stupidity fueled by greed.
Personal titles aren't something which motivate me.
