It's in the valley of failure that we sow our seeds of success.
Only worry about your own happiness, which doesn’t have to be limited by anyone else’s stupidity unless you allow it to be.
Teaching how to think is better than lecturing how to do it.
Luck is created by the prepared.
When the lights come on inside of you, everyone in the world can see a little better.
Success comes from continually expanding your frontiers in every direction-creatively, financially, spiritually, and physically. Always ask yourself, what can I improve? Who else can I talk to? Where else can I look?
