I think there's competing issues here, there's an aspect of "I want to prove myself" by creating something really good and unique that I can be proud of. There's also the "do good" aspect of potentially creating something that's a "force for good". Doing either one of those is hard, doing both at the same time is probably very very hard. You both need to chase down a good idea but also execute it well. If you want to do good for the world, honestly finding a charity that would benefit from your cash and making a donation would do that. But that won't scratch your nagging itch to make something you can be proud of. For that, perhaps saving up enough money to allow you to quit or take a sabbatical if one is possible to work on the thing you want to is a better idea. Would it be better for your career? Perhaps not, but it might scratch that itch and that might be better for you as a person.
