Be kind, be witty, be aggressive, be patient, be gentle, be charming, be understanding, be successful, be well-rounded, be strong. Don't just be these things, be the right amount of them, and be them all of the time. Be Superman, and Batman, and Bill Gates, all before noon. Be impossible.
"Want to be rich? Just work 23 hours a day, for the next 6 years."
This is just as terrible a plan for success, and just as likely to fail.
Perfection, like happiness, is a mindset. Perfection is contentment meets confidence. A centering of self with an understanding of what your needs are. That the pursuit of perfection is also the road to excellence.
It is not that the woman who's "perfect" at her job doesn't have problems, it is that she addresses them effectively and attains her goals anyways.
It is not that people in "perfect" relationships don't have problems. Conflict resolution is the cornerstone of successful relationships. "Perfect" couples successfully fight, claw, identify, disagree, discuss, kiss, fight some more, and meet in the middle. They have, essentially, perfected the inevitable imperfections that will arise. They'll laugh about it later, and you'll wonder how they're so perfect.
The trick to perfection is not to avoid mistakes, mistakes cannot be avoided. The trick is to build a strong enough base so that your bad days are still good enough. So that your shortcomings become springboards. Be honest, be yourself, be persistent, be excellent. That's perfect.
