That is good advice, and much better than the columnist's! "Listening to your coach is a vital sports skill" is something that LW might even be able to hear and take on board.

Some LWs really do suck but I think people who are paid to give advice should at least TRY to give them some actionable advice, rather than talking about their own issues for paragraphs and then ending on "you're bad and should feel bad." (Kibitzers like us are under no obligation to be useful, of course! But Doyin is supposed to be doing a job.)
