"Success is inevitable only in hindsight. It's easy to look back on another person's path to greatness and assume that every vision was clear, every plan was perfect, every step was executed flawlessly, and tremendous success was a foregone conclusion.
It wasn't. Success is never assured. Only in hindsight does it appear that way.
Maybe you think the odds are against you. Maybe you think the path you've chosen is too hard. Maybe you think you may not be good enough.
Stop thinking that way. Stop measuring yourself against other people. Stop measuring yourself against what think you deserve, or against the opportunities you think you should have.
Pick a goal and measure yourself against that goal -- that is the only comparison that matters. Strive to be the best, at whatever you choose, that you can possibly be. Define success your way, and then work to achieve your definition of success."
