The only limits on human achievement are self-imposed.

Virtually nothing on earth can stop a person with a positive attitude who has his goals clearly in sight.

Time is the most precious element of human existence. The successful person knows how to put energy into time and how to draw success from time.

The only limits on human achievement are self-imposed.

Perseverance does not always mean sticking to the same thing forever. It means giving full concentration and effort to whatever you are doing right now.

Achievers can almost literally taste success because they imagine their goals in such vivid detail. Setbacks only seem to add spice and favor to the final taste of victory.

Motivation is an inner force that compels behavior.
