Are any of you guys pursuing music with nothing to fall back on?

Other than a minimum wage job? How’s it going. What are you guys doing to make it liveable especially in a hcol. And how old are you guys and around when did u guys start to pursue music. I’m 23 and I feel like it’s too late to me bc I never started. I have now or never either go to college for a career that when I garaduate I’ll be making shit salary anyways. Or pursue what I’ve always been curious and yearning for.
