I think this is one perfectly valid approach to life, but certainly not the only one. Working a job you don't enjoy (but that isn't soul-sucking) but that pays you very well, so you can quit more quickly and not have to work at all is also a perfectly valid approach to life. Working jobs that feel neutral but allow you to take periodic sabbaticals? Also good. Or maybe you have a rando but decent paying job during the week and on the weekend you work a few hours at a horse barn, feeding your equestrian yearnings but also having a steady paycheck, a job that is less hard on your body (a concern longer term), and paying you enough to have the 5 kids you always dreamed of or to live close to family in a HCOL city.
I know if doesn't get Youtube clicks or sell self-help books, but the fact is there is more than one way to live a great, fulfilled life. So much of this depends on individual preferences and abilities. (If that person who wants to be a painter has no skill whatsoever at painting, it's probably not going to be a good choice for him to "do that", and that alone.) And even for one specific person, there is surely more than one way to find happiness while also feeding one's belly.
