If you would one day renovate yourself, do so from day to day

Only the wisest and the stupidest of men never change.

If you do not change the direction in which you are going, you will end up where you are headed.

They must often change, who would be constant in happiness or wisdom.

When you meet someone better than yourself, turn your thoughts to becoming his equal. When you meet someone not as good as you are, look within and examine your own self.

The faults of a superior person are like the sun and moon. They have their faults, and everyone sees them; they change and everyone looks up to them.
