Don't feel bad for making decisions that upset other people. you're not responsible for their happiness, you're responsible for yours.

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful

Without some goals and some efforts to reach it, no man can live.

You can't hit a target you cannot see, and you cannot see a target you do not have.

Sometimes your joy is the source of your smile, but sometimes your smile can be the source of your joy.

I am always doing that which I cannot do, in order that I may learn how to do it.

In the kingdom of the blind, the one-eyed man is king.
