For guidance on this topic, I’d recommend the book “Deep Work” by Cal Newport. I think the relevant part of the book would advise that loving what you do requires sticking with it long enough to develop mastery; and the opposite pattern of bouncing between topics “looking for passion” is a recipe for mediocrity and dissatisfaction (I’m probably overstating his case a bit). But the whole book is great!

It was the "so good they can't ignore you" book of his.

With that said, both books are excellent. In my opinion "so good they can't ignore you" explains why you should want to become very good in something, and the "deep work" explains how to become good in something.
