Pushing this topic in another direction.
I'm noticing a very common trait with the hyper-successful. They always talk about not fearing the pain, the despair, and the failures. The theme is always to embrace it, let it wrap around you, and pull the ******* pain with you.
I remember when I first started working out. I was obese as ****. I hated looking at myself in the mirror. And honestly I know every out-of-shape fat **** feels the same way. I call them fat fucks because that's what I still call myself. I am significantly stronger, and faster than most but in my mind, I am a weak, fat, stupid, imperfect, flawed, sack of **** that is ready to quit every god damn day. There's somebody out there stronger. There's somebody out there faster. There's somebody out there who has better genetics, outputting 10% of my effort, and kicking my god damn ass.
One of my ex-managers was really good as a manager....except he was so damn insecure. The dude is obese. I have no issues with coming to work and screaming "I JUST BROKE MY DEADLIFT PR OF 405LB, I WEIGH 160." Every time he'd get insecure. He would flip the focus and say "I can't work out because I have arthritis." Or it'd be that kids take too much time. Or too much pain. Whatever.
...I was never trying to trigger him. I just wanted to celebrate a victory, because they come very rarely (twice a year?), with people I see everyday. The girls across the room would congratulate me, sometimes asking me to "wink" my pecks. The CEO would always be very impressed because he used to be a marathon runner. But my focus was on my manager and the god damn weakness he was exhibiting. The bleeding insecurity. The realization that he is literally an alternate version of me. The coward I was, and can easily become. The default state that every one of us are born into.
I do not want to ever go back to that state.
