I don't think our personal passions are the most important things in the world.  I don't even think they are the most important things to us individually.  They are merely the things that refill us.  Things that charge our batteries.

Maybe it's a bad (or overused) analogy, but in this sense, I think we are kind of like cars.  Cars need fuel to go.  No gas, no go.  Sure, you can sometimes get a little further grinding the starter once the fuel is gone, but you won't get very far and you won't get there fast. 

People need to fuel their passions.
