Success is a lousy teacher. It seduces smart people into thinking they can't lose.
In order to succeed, your desire for success should be greater than your fear of failure.
By failing to prepare, you are preparing to fail.
I have not failed. I've just found 10,000 ways that won't work.
Success consists of going from failure to failure without loss of enthusiasm.
Failure is simply the opportunity to begin again, this time more intelligently.
