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

Do not speak of your happiness to one less fortunate than yourself.

Happiness depends more on how life strikes you than on what happens.

Happiness lies in the joy of achievement and the thrill of creative effort.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Be happy for this moment. This moment is your life.
