You can only achieve happiness if you are too busy living your life to notice whether you are happy or not. People are always blaming their circumstances for what they are. I don't believe in circumstances. The people who get on in this world are the people who get up and look for the circumstances they want, and, if they can't find them, make them. Our greatest battles are that with our own minds.
Some people are so afraid to die that they never begin to live.
The importance of humility. We need the humility to know that truth can be ephemeral, that this can be but one version of the truth. Make them expeditiously, and stay with them as long as you believe you are correct no matter what others say. However, when you conclude you were in error, do not hesitate to announce the error publicly and change course. The purpose of life is to grow and to share.
