The biggest lesson I have learned is the stupendous importance of what we think. If I knew what you think, I would know what you are, for your thoughts make you what you are; by changing our thoughts, we can change our lives.

If you argue and rankle and contradict, you may achieve a victory sometimes; but it will be an empty victory because you will never get your opponent's good will.

When you face a problem, solve it then and there if you have the facts necessary to make a decision. Don't keep putting off decisions.

Success in dealing with people depends on sympathetic grasp of the other person's viewpoint.

You can sing only what you are. You can paint only what you are. You must be what your experiences, your environment, and your heredity have made you. For better or for worse, you must play your own little instrument in the orchestra of life.

It isn't work that makes you tired, it's your mental attitude.

If you want to be happy, set yourself a goal that commands your thoughts, liberates your energy and inspires your hopes. Happiness is within you. It comes from doing some certain thing into which you can put all your thought and energy. If you want to be happy, get enthusiastic about something.
