Man alone is born crying, lives complaining, and dies disappointed.

If you dream of something worth doing and then simply go to work on it and don't think anything of personalities, or emotional conflicts, or of money, or of family distractions it is amazing how quickly you get through those 5,000 steps.

Because of a great love, one is courageous.

Men have become the tools of their tools.

If you can find a path with no obstacles, it probably doesn't lead anywhere.

Technology is nothing. What's important is that you have a faith in people, that they're basically good and smart, and if you give them tools, they'll do wonderful things with them.
