Earlier quoted context omitted.
You won't ever get big with this scheme but you can be sustainable.
There should be more people striving for sustainable businesses IMO.
It's not like there aren't people focused on sustainable businesses. 90% of businesses are probably SMBs - just not in tech. For most people in the world, the word entrepreneur means "someone who's opening a McDonalds across the street" or "someone opening a pizza shop". Even in tech, there are plenty of not-hypergrowth companies around (I run a small dev shop, for example).
The reason we here are exposed more to VC-style startups is because a) they make more news, for obvious reasons, but also b) there are structural reasons in tech that favor that style of company, most importantly because software itself is scalable in a way that most things aren't.
