It is our nature to conform; it is a force which not many can successfully resist. What is its seat? The inborn requirement of self-approval.

It may be called the master passion, the hunger for self-approval

We can secure other people's approval, if we do right and try hard; but our own is worth a hundred of it, and no way has been found out of securing that

A man cannot be uncomfortable without his own approval

What do you call love, hate, charity, revenge, humanity, magnanimity, forgiveness? Different results of the one master impulse: the necessity of securing one's self-approval

Don't challenge resistance. Don't resist challenge.
