Or don't, and cultivate taste, which is about having a rationale for separating the good from the bad -- and disliking stuff. It might not make you popular at parties though.

What they are saying is that you can make yourself enjoy a field _at all_, in which you can then apply taste. For example I don't like whisky, but that's not a matter of me applying "good taste": I would never claim that whisky is bad in general and if I really tried I'm pretty sure I would start being able to enjoy whisky and separate the good from the bad (at least subjectively).
