The difference between intelligence and an education is this: that intelligence will make a good living for you, but education won't do much for you at all.

The opportunities in this world are as great as we have the imagination to see them... but we never get that view from the bottom of the nest.

We work day after day, not to finish things; but to make the future better ... because we will spend the rest of our lives there.

99 percent of success is built on failure.

The world hates change, yet it is the only thing that has brought progress.

I expect to spend the rest of my life in the future, so I want to be reasonably sure of what kind of future it's going to be. That is my reason for planning.

We need to teach the highly educated man that it is not a disgrace to fail and that he must analyze every failure to find its cause. He must learn how to fail intelligently, for failing is one of the greatest arts in the world.
