I find myself in a similar situation - a friend's perspective is that you can learn from anything. Mine is that you should triage endlessly after a certain point, I guess that makes me dismissive.

Of course, if I told him "So, you can browse facebook all day and be better off?", he would probably say "You know what I mean."

Real "wisdom" is knowing when to be dismissive and when not to be, either extreme is bad, but being able to discern is tacit knowledge that no one can really say anything useful on without being super specific.
