> No problem is too small or too trivial if we can really do something about it.
I think we often forget this. Especially in our fast paced world and career. But often it is the little things which are hard to get right and also the things that create the most problems.I think we try to think we can predict what are important problems and what are not. Sometimes this is easy and we're right, but often we aren't. This is true in math, physics, and computer science. In any domain. So do what you like because you never really know. Plus, they say interest is worth an extra 10 IQ points.
From all my reading of Feynman I think there's one thing he'd stress: have fun. To never lose the creativity, that child like wonder. In CS we got here because we loved to play around and hack. I hope we never lose that.
