I can never pick up a thing without wishing to improve it.

There is nothing wrong in change, if it is in the right direction. To improve is to change, so to be perfect is to have changed often.

A lot of the things that will really improve the world fortunately aren't dependent on Washington doing something different.

To improve is to change; to be perfect is to change often.

There is a subtle danger in a man thinking that he is "fixed" for life. It indicates that the next jolt of the wheel of progress is going to fling him off.

Hardships exist to make me stronger, helping me grow and improve, not to leave me hopeless or discouraged.
