“My difficulties belong to me!” — Alfred Adler

It is always easier to fight for one's principles than to live up to them.

There is no such thing as talent. There is pressure.

There is a law that man should love his neighbor as himself. In a few hundred years it should be as natural to mankind as breathing or the upright gait; but if he does not learn it he must perish.

To be a human being means to possess a feeling of inferiority which constantly presses towards its own conquest. The greater the feeling of inferiority that has been experienced, the more powerful is the urge for conquest and the more violent the emotional agitation.
