If you're constantly pushing yourself higher, higher, the law of averages - not to mention the myth of Icarus - predicts that you will at some point fall. And when you do, I want you to know this, remember this: There is no such thing as failure.
Surround yourself only with people who are going to take you higher.
Lots of people want to ride with you in the limo, but what you want is someone who will take the bus with you when the limo breaks down.
Every stumble is not a fall, and every fall does not mean failure.
Where there is no struggle, there is no strength.
You are responsible for the energy that you create for yourself, and you're responsible for the energy that you bring to others.
