You're asking the reverse of the question I'd be asking. Purpose, money, and satisfaction are so vague and general, you'll never find an answer from those premises alone. What do you care about? Music? Your family? Friends? The environment? Cooking? Poverty? Writing? Abstract mathematics? I hope at this point you have an idea of some things you enjoy or excite you, and you can work forwards from those. But with what you've given us, there's just not enough to work from. Aimlessly looking for purpose is kinda an oxymoron. From the things you enjoy or excite you, start thinking about how to make that your day job. Or alternatively, start thinking about how to have a chill flexible day job that allows you to do those things more in your own time. Try things out that you already think are cool, and maybe something will stick. Then you can work towards that.
