I remember having issues with pulling out rounded bleeders all the time when I had first hit the fleet as a mechanic in the military. After like 20 of them one of my Corporals saw me struggling and came over and did that drill bit trick and got it out in like 45 seconds. I just sat there fuckin dumbfounded for like 10 minutes. He told me “just because you’re busting your *** doesn’t mean you’re actually accomplishing anything. Use your fuckin head”. That moment shaped the way I worked on anything since.
