Great leadership involves three things. The ability to realize when you are wrong, a willingness to learn from it, and an eagerness to change course if necessary.

Nothing in the world can take the place of Persistence. The desire and ability to press on has and always will solve the problems of the human race and divide those who achieve from those who might have been.

we must ceaselessly safeguard, promote and develop the interests of the masses.

The thing that we possess, that machines don't, is the ability to exhibit wisdom.
