n0 > Learning them isn’t what makes one a chossid.
n0, thanks for the correction, of course it is “doing” (lekayam, BK 30a). But that requires learning (lo am haaretz hasid) first, and as we are discussing learning, I got carried away and misquoted… My apology.
Of course, the next question is whether learning leads to doing it, I did not want to run away from that question. So, say someone learns nezikin, but did not accustom himself to do it all the time. Should he skip avos and go to brochos, or should he first take a semester off and practice nezikin?
If we take a high road and say – mishna is meant for someone who already learnt everything, and now needs to focus his maasim in one area, it is still unclear – was he simply learning before and not doing any of them? maybe, with f/t learning and no opportunities to interact with people, and now preparing for that?
