If there is no fun in it, something is wrong with all you are doing.

A vital part of the happiness formula is self-discipline. Whoever conquers himself knows deep happiness that fills the heart with joy.

Good will cannot flow toward you unless it flows from you.

If you want a quality, act as if you already have it. If you want to be courageous, act as if you were - and as you act and persevere in acting, so you tend to become.

One of the greatest of all principles is that men can do what they think they can do.

If you feel afraid, you can make yourself courageous by acting courageous. If you are feeling unhappy, by deliberately acting happy you can induce happy feeling. If you are lacking in enthusiasm, by simply acting enthusiastic you can make yourself enthusiastic.

Learn from both your mistakes and successes because if you learn only from your mistakes you will only learn more errors
