When you're working for yourself, you're still working for your customers. This notion that working on a fulfilling business can meet all of a person's needs is false. Working on something fulfilling, for money is good. Having the option of doing something fulfilling that doesn't need to make money is better. So, back to the OP's point: FU money is better than a happy income (depending on what you have to do to get to the FU stage).
