The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress.
The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.
