You become perfect by making each mistake once and learning from it, eventually you wont have any mistakes left to make.
I made a HUGE mistake today, one that will cost. I made a huge mess of the final coat of paint on the fuselage. Forgot to adjust the paint flow knob before spraying so it was WIDE open. It was sickening, all 9 coats of perfect paint messed up by the final coat running. Lesson learned. After cleaning spray gun ALWAYS set the flow knob. There is NO excuse for not doing this each time before spraying BUT there is no reason to invite human error. Setting it correctly twice costs nothing. Forgetting to set it at all is VERY costly as today showed. Live and learn. Make each mistake only once and eventually you wont have any mistakes left to make.
Don’t be afraid of making mistakes. If you want to be afraid of something, be afraid of repeatedly banging your head against the wall and not learning from your mistakes. Todays example was courtesy of my spray gun but fitness mistakes are just as common. Maximizing strength and muscle gain is not a pure science, don’t be afraid to experiment BUT learn from your mistakes and follow the scientific method so your results have meaning. If you haven’t gotten any stronger in the last 6 months, then you are making a mistake! Learn and move on! If you tore your rotator cuff and need surgery then you made a mistake, own it, it wasn’t an “accident”. Learn from it and make sure it doesn’t happen again.
