You don't have to justify yourself for quitting your boring full-time job. Most people don't have that option and you're in a fortunate position. I wish I knew more people like you with the courage to actually quit once you're able. I have too many friends who continue to slave away, complaining about their jobs, yet have banked 7 digits+, all because they think that they'd feel out of place and without things to do if they quit, or just want to continue accumulating more money. I don't see a reason to accumulate money if you have no time to spend it.
