The point being that you should do what you love, and worry about money second.
Sometimes you're glad you followed your heart into nursing. You certainly make the world a better place, and your finite life has been lived with honor. But do you ever find yourself wishing for a life of utter sloth? A life in which money is truly no object, because Uncle Steve left you 500 million dollars?
Shit. I do. Design reads: "sometimes i'm glad i became a nurse, other times i wish i had simply inherited a trust fund."
