Yeah, the species does better when people never give up because the species can afford to have many wasted lives in return for the advances that can come from the ones that don't fail. It's a little different for individuals, who, for all we know, have only the one life and maybe don't want to spend it trying to suck a bit less at guitar.

Though I would say to give things a fair chance because the first step of being great at something you love is almost always kinda sucking at something you aren't sure about. But I'm trying to find a healthy medium between making sure she tries things but isn't stuck doing them until she burns out with my daughter.
