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.
fill your soul. feed the world.
