I think this is bad advice. "Does it bring you satisfaction" should not be the only factor for making decisions.

Even if you get plenty satisfaction from work, I think its important to invest in other parts of your life (family, health, hobbies).

That's a great argument to continue consuming drugs. It is not just what you get, you also need to take a look at what you miss.

Been satisfied with what you have is a good thing. But should not stop you of seeking better things.
