It is hard to keep that which has not been obtained through personal development.

Good people are found, not changed.

Your paycheck is not your employer's responsibility, it's your responsibility. Your employer has no control over your value, but you do.

Work harder on yourself than you do on your job. If you work hard on your job, you can make a living. If you work hard on yourself, you can make a fortune... Income seldom exceeds personal development.

Make measurable progress in reasonable time.

It can be dangerous to weaken the strong in our attempts to strengthen the weak.

Emotions are the fuel and the mind is the pilot which together propel the ship of civilized progress.
