Yes but there's no advice on how to take it easy. It's just saying to do so, which is pretty unoriginal advice. Why recommend that someone take it hard, grudgingly, or angrily? It feels less sincere because there's no personalization to it. Maybe "vague" wasn't the right word, instead I'd call it "generic".
I see "take it easy" to mean something like "try to live your life in such a way that you can still be productive/effective/whatever without stressing out about things in ways that would raise your blood pressure unnecessarily. If something is important, feeling anxious about it doesn't make you any more able to accomplish it. You can think about something to plan it; and you can think about something while you're doing it—but outside of these productive uses of your mental energy, you should never let anything weigh on, or especially linger in, your mind. This will make you live longer, which will make me happy as I won't have to see you die before I do."
Of course, most people don't really know what they mean when they say it—but their intent usually lines up with the paragraph above.
