Cromwell, I charge thee, fling away ambition: By that sin fell the angels ...

There is a loftier ambition than merely to stand high in the world. It is to stoop down and lift mankind a little higher.

The vague torment of ... ambition.

The trouble with being number one in the world at anything is that it takes a certain mentality to attain that position in the first place, and that is something of a driving, perfectionist attitude, so that once you do achieve number one, you don't relax and enjoy it.

Go for the moon. If you don't get it, you'll still be heading for a star.

Ambition, if it feeds at all, does so on the ambition of others.
