Seriously, the pilot we SHOULD worry about is the one who doesn't want to go around!
Aborted landings are a daily event, and quite frankly should probably happen a lot more than they do.
I've had a handful of near touchdown aborts and every time I've found myself grateful that the pilot had the sense (and humility) to say "let's try that again" rather than trying to stick an improper approach.
