Everyone in the world wants to make money because it is the most powerful/influential thing in this world. Yet being motivated by money is a different thing entirely. It's like saying would you kill someone for all the money in the world? Most people would say no due to their morals, however others would accept it immediately. It also depends on the circumstances of a person, how much money is involved and the requirements around it.
All be it being motivated by money is not a bad thing, it just means you want to become successful and make your life a little easier in regards to financial strength. However others make money for darker motives and would do literally anything. Me personally I am motivated by happiness, I have no need for royalties as long as I am as happy as can be.
