I think this is a pretty important point. Often times I think I'm interested in doing something or I like the idea of it, but it doesn't take me very long to realize that I'm completely disinterested because of the actuality of the thing. I'm OK with that.
I think the parent is probably trying to say that you definitely haven't done enough exploring on most subjects in a short time to find and glean all the interesting bits, and I agree with that as well. There are work projects that I would have abandoned long ago if they were personal projects that I have got A TON out of by sticking with them and working on them for years. But in those years there has been a lot of slog as well, and it's probably not the optimal way to mine all the knowledge nuggets...
