This is good advice. And as far as "single-player" activities are concerned, I think pursuing curiosities as far as your interest will go is a good way to discover new interests. Read an article on a topic you find compelling? Find additional reading material. Maybe take a class. Catch the urge to make something? Go for it. Something might stick or it may not. Either way, you'll have done something you might not have otherwise done and it won't have been a waste of time.

As we get older, we develop stronger biases, so we think we can dismiss more and more as not worthwhile without even trying it. That's why I believe some outside influence is key.
