I'm curious. The business you started, were those businesses you had gained experience before hand? As in worked for another company doing the same?Speaking as someone who has started and failed at two businesses already, what you're proposing is also based on hope.
Most businesses fail. Human beings are stupidly optimistic, otherwise we wouldn't even bother.
IMHO, you're much more likely to get the "freedom" that @RedViking talks about by saving and investing but also by simplifying.
I'm done with the stress of running a business for now. Maybe one day I'll try again but I much prefer having a normal job.
What I've noticed that most people would delve into a business they have no clue about. That's mostly a guarantee you'll struggle.
It's far easier to create a business from something you are good at already. Don't look too deep, just look down at your feet. You are already standing on a business opportunity.
