Another perspective from the other replies: lean into that motivation. I’ve found that there are few projects more rewarding than ones done for money - not necessarily because of the money itself - but because to convince people to part with their money you have to make something they really want. You’re solving a problem for them, making them happier, making their life easier. You get feedback about how much they appreciate it. You meet with others who are doing the same thing and want to work with you. You get noticed as being a helpful and competent person.

The money is just a proxy for how much value you make for people and that feels good and challenges you in ways you wouldn’t expect.
