We may all be experts at something; we are all certainly terrible at most things. Stop worrying and start doing.
I’m not saying there aren’t experts or that training is useless. I’m glad our nuclear reactors are built by guys who didn’t learn by swinging hammers at hunks of uranium. But every expert was once a dumb jerk who said, “I am smart enough to figure this out,” even though he had no rational foreknowledge of whether that were true.
[W]ith the whole of human experience just a few radio waves away, it’s never been a better time to be a big, fat liar.
Or to use confidence for good.
