Keep your mind open to change all the time. Welcome it. Court it. It is only by examining and reexamining your opinions and ideas that you can progress.
If you want others to like you, if you want to develop real friendships, if you want to help others at the same time as you help yourself, keep this principle in mind: Become genuinely interested in other people.
The most important thing in life is not simply to capitalize on your gains. Any fool can do that. The important thing is to profit from your losses. That requires intelligence, and makes the difference between a man of sense and a fool.
Are you bored with life? Then throw yourself into some work you believe in with all your heart, live for it, die for it, and you will find happiness that you had thought could never be yours.
