Ah but.
A pilot displaying an appropriate level of professionalism, is surely doing all of these things.
I happened to talk about stalls and PFLs in the other thread, but equally practicing basic flight planning, doing W&CG regularly, putting effort into ensuring good landings, reviewing the POH periodically: all are part of the same thing - showing the sort of professionalism in your routine flying that ensures (hopefully) being able to deal with things when they get a bit hairy or, better still, ensuring that they never get hairy in the first place.
