I am not sure one size fits all with poker and studying, so I try to avoid regulating myself.
Don't get me wrong, I think anyone with even the slightest ambition needs to constantly review their own play and turn to whatever learning aids interest them. But I do think many get caught up in a cliched view of what constitutes learning when the real path is that of self-discovery/awareness and which particular learning paths/style of play suit your character.
Some have given study (in a conventional sense) something of a wide berth. Bryn Kenney for one has never used solvers and vows not to (he does have a photographic memory) but there are other players such as Dan Colman who also claim they have ever done little more than discuss hands with friends.
Its been illuminating to follow all the brouhaha about GTO play. For the last five or so years the poker media constantly reported the GTO wizards and style of play would completely take over poker. It was a silly assumption - GTO has its place but evidently GTO and its exponents are not taking over the game.
As for myself, I think I am generally open (watch videos, listen to podcasts regarding coaching every week) but also like to take a really hard line with my own play to overhaul and improve it.
Finally, I am one of those who thinks , above all, nothing beats playing a vast amount of hands against an endless field of diverse players.
