I spent 10 years enlisted (sheet metal/boom operator) and thought that I would destroy the non-priors when I walked into UPT, I was wrong!  Flying an aircraft is harder than it looks.    The quote mentioned above is right on point.  UPT is a place where you can't ###### around.   The competition is fierce and no one gives a ###### about what you did before.... Do your best and hope the cards line up in your favor!
