Come to think about it, one year isn't enough,
I find it intriguing that, for most of us who don't have too high an opinion of our innate knowledge .... start off knowing nothing .... a year or two later (as young bucks with a few hundred hours) know that we know everything .. and then spend the rest of our careers coming to realise just how little we really do know.
Those of us who might end up experts, of course, understand that an expert is someone who knows an impressive amount about next to nothing, a workmanlike amount about a number of other useful things .... and zip about near everything else.
Learning commences with humility.
OS, salut !
