Seldom are we remembered for the things we don't do. Most of our errors are errors of inaction rather than action. Yet, it's our errors of action that we remember because they're tangible, embarrassing, hurtful, and make us feel ashamed.
We fear mistakes for the criticism affiliated with imperfection. But don't hold your breath waiting for perfection. It's a myth. Like chasing the elusive "end of the rainbow", the closer you get, the further it seems until suddenly you look up and the color has vanished.
Perfection is an admiral goal, but if you spend your life chasing rainbows you may feel you're missing out. However, if you wake up each morning grateful for the life you have (not what you think you should want) you may actually find satisfaction in imperfection.
I love that I'm not six feet tall. I love that my abs are not sculpted like the statue of David and that I take the train to work rather than drive in an expensive car. No worldly possession will make you feel better about yourself than you can. It's people and their imperfections that bring us the most joy.
Perfect is not a mythological creature we should spend our life pursuing. It's you, as you are, today. The moment you realize this, the pressure is off. The helm of your life becomes yours to steer and it's by sailing steady in the direction that brings us happiness that we add the most value to the world--not our failed attempts at perfection.
Don't make errors of inaction. Just go start.
