Scientists: What do you consider your prime motivation for practising science?

Curiosity and confidence in figuring things out are probably my strongest reasons.

I have a fairly strong sense of what is real, perhaps an insight, and like to apply that sense to test it out on the world. Sometimes I'm wrong but in that case I get corrected. Some puzzles are very difficult, the more difficult the better.

Most scientists' motivations are pure and noble. But the corporations they work for are mainly motivated by developing and perfecting nuclear weapons and winning wars.

Keeps me young and open to new ideas. Honestly, there are more ideas in science or in disciplined thinking than in any marketing think tank.

I've always been an explorer. I call it mind exploration.
