I've seen guys who make very, very few mistakes (and been appropriately jealous) but I can't recall anyone who never made any at all ...
No point in arguing the toss as to how great one is .. the other guys have already seen one's screw up(s) from their relaxed non-PF seats of comfort.
Surely the only sensible way ahead is to admit the deficit to oneself, fix it, and move on ?
And we all had a bit of trouble getting on top of the brawny arm PIO during endorsements and early training flights ...
