You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time. My great concern is not whether you have failed, but whether you are content with your failure. Nearly all men can stand adversity, but if you want to test a man's character, give him power. Better to remain silent and be thought a fool then to speak out and remove all doubt. Things may come to those who wait, but only the things left by those who hustle.
Most people are about as happy as they make up their minds to be.
Tact is the ability to describe others as they see themselves. He has the right to criticize who has the heart to help. I destroy my enemy when I make him my friend. While one person hesitates because he feels inferior, the other is busy making mistakes and becoming superior. The difference between a successful person and others is not a lack of strength , not a lack of knowledge, but rather a lack of will.
