Nothing is perfect on the human stage.

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.

Perfect solutions of our difficulties are not to be looked for in an imperfect world.

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

When a man is perfect, he sees perfection in others. When he sees imperfection, it is his own mind projecting itself.

Every kind of perfection is purchased at a high price on earth, where everything is perhaps purchased too dear; one is an expert in one's department at the price of being also a victim of one's department.
