Challenge, challenge and more challenge... I don't enjoy doing things like a robot. I love to put some new ideas out there to see how everything results in constant progress... because of me!!!^^ That is my main motivation and it keeps my attitude (seriously) flying all over the place. :)

You could say something along these lines: "I enjoy making [or helping to make] this kind of system work." or, "I find it very satisfying to put out a high quality product." or, "I get energized by a challenge, and know how to work with others to find a solution."

I like your picture ,it motivates me :P

the money?

Your true aims and wishes (not parent's or society's) - the best motivation.
