The only constant factor in life is our feelings and attitudes toward life. One of the few things that we have total control over is our own attitude.

The most valuable form of discipline is the one that you impose upon yourself.

Attitude is your acceptance of the natural laws, or your rejection of the natural laws.

Discipline means we don't let go of the things we know we should be doing, we do them!

Every time we choose action over ease or labor over rest, we develop an increasing level of self-worth, self-respect and self-confidence. In the final analysis, it is how we feel about ourselves that provides the greatest reward from any activity. It is not what we get that makes us valuable, it is what we become in the process of doing that brings value into our lives. It is activity that converts human dreams into human reality, and that conversion from idea into actuality gives us a personal value that can come from no other source.

The best advice I ever came across on the subject of concentration is: Wherever you are, be there.

Don’t blow your own horn, or you might just miss the music.
