Laugh at yourself and at life. Not in the spirit of derision or whining self-pity, but as a remedy, a miracle drug, that will ease your pain, cure your depression, and help you to put in perspective that seemingly terrible defeat... Never take yourself too seriously.

I will not allow yesterday's success to lull me into today's complacency, for this is the great foundation of failure.

God will never give you any problems that he thinks you can't solve.

Realize that true happiness lies within you. Waste no time and effort searching for peace and contentment and joy in the world outside. Remember that there is no happiness in having or in getting, but only in giving. Reach out. Share. Smile. Hug. Happiness is a perfume you cannot pour on others without getting a few drops on yourself.

I'd rather learn how to prevent failure than how to gain success, because for what is success other than a state of mind?

I have never heard anything about the resolutions of the apostles, but a good deal about their acts.

Each failure to sell will increase your chances for success at your next attempt.
