Every time we think we notice another person's mistake we can delude ourselves that we are superior to them, but it is only when we notice our own mistake that we can be sure that we are surpassing ourselves.

I am available to make mistakes, I only prefer to make new ones.

There are things done so badly that one is tempted to think that there is an intention behind.

There is one thing worse than making a thing wrong: doing badly a right thing.
