Retire into yourself as much as possible. Associate with people who are likely to improve you. Welcome those whom you are capable of improving. The process is a mutual one. People learn as they teach.
Look not mournfully into the past. It comes not back again. Wisely improve the present. It is thine. Go forth to meet the shadowy future, without fear.

The ''Inside-Out'' approach to personal and interpersonal effectiveness means to start first with self; even more fundamentally, to start with the most inside part of self -- with your paradigms, your character, and your motives.

It says it is futile to put personality ahead of character, to try to improve relationships with others before improving ourselves.
