I'm a man of the present. I have no keepsakes and I don't harbor pipe dreams. But I would like to learn how to pick locks, which is, incidentally, what I'm doing right now.

I think it was Neil DeGrasse Tyson who said something I found very inspiring. It went something like "you may or may not be able to become great at something, but you can always become better at it."
