Well............................................
"Worry a little bit every day and in a lifetime you will lose a couple of years. If something is wrong, fix it if you can. But train yourself not to worry. Worry never fixes anything."
However
"Real happiness is not dependent on external things. The pond is fed from within. The kind of happiness that stays with you is the happiness that springs from inward thoughts and emotions. You must cultivate your mind if you wish to achieve enduring happiness. You must furnish your mind with interesting thoughts and ideas. For an empty mind seeks plearus as a substitute for happiness."
And
"Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to the end, requires some of the same courage which a soldier needs."
