That would certainly be in line with current thinking in the commercial flying world.
I recently attended an aviation safety conference aimed primarily at CAT and Aerial work, which was looking at what needed to be done to further improve safety.
Professionalism in the cockpit was the catchphrase, and was set out by many speakers as; if you always aim to fly as well as you possibly can, your skills remain sharp for that one time you really, really need them to be. If you fly sloppily because 'it doesn't really matter' on a routine flight, then your finer skills atrophy and aren't there to call upon when it really counts.
Although this was aimed commercial flying, I have taken this to heart for my own leisure flying, as it not only makes sense but also mirrors what my instructor always tried to drum into us.
