Value from the brain


Am I getting this concept wrong?
I do believe that I create money with my brain. I interpret it as: I create value with the ideas of my brain that people will be willing to pay for. I do need to exchange the value for other value (money) or not? I believe I need a “transaction” in order for the money to be in my pocket.
Or, am I supposed to believe that I materialize money from my brain?
Please explain.
