There’s really no big mystery to making more money. There’s no big secret that only rich people are privy to, and absolutely no proven formula that only the wealthy have access to.
To the degree your art is extraordinary, your product is exceptional and your service is above and beyond, to that degree more money will flow your way. And it doesn’t matter how unfair you think the system is or how much more loot others are raking in. The only thing that matters is that you offer us something that’s irresistible, something we simply must have, and something we simply must share with others. If you do that, we’ll “direct deposit” dollars into your account.
