How Did You Unintentionally Create a Business?

I learned programming out of absolute necessity, but now that I know how to program, I think of how I can not just solve it, but like solve it for the world. It's fun to think how I could make this a system that everybody can use. But yeah, I think that kind of thinking came later after I started CD Baby, actually. "It was only out of necessity when musicians kept asking me to sell their CD, too"
