What kind of business? Most of the dream ones people envision are capital-intensive and failure-prone (speaking as someone who started a capital intensive business that failed)
The only small businesses I know that are succeeding in my area are basically services - restaurants, cafes, etc. They rely on exploiting a bunch of underpaid workers in a way I wouldn't ever want to.
In your other comment it sounds like you're just kind of doing "handyman" stuff in a low CoL area. It's great if you can handle your own plumbing, electrical, etc. but there's definitely a ceiling on how much work you can get as a single, unlicensed person with a van driving around. Maybe that's enough to live on but it doesn't feel like a sustainable plan for 30 years.
