As a guy who does small business IT type shit (think of the worlds smallest MSP, then think smaller?) the key is to start small in your time off. Go on upwork (which is an absolute shithole) and find out if you like short term (like this weekend) contract semi-skilled labor.
Also there's a BIG difference between not liking being a landscaper (or maybe liking it) versus owning and managing a landscaping company.
Another point is good enough is the enemy of perfect. Your first company idea will probably fail so it doesn't matter if you like mowing lawns go be a landscaper anyway.
If you can read, write, and speak English, and you're reliable and not high all the time on some drugs, you're ahead of about 95% of the competition in several fields such as landscaping which is why I use that as an example. What you learn managing a small time landscaping company will pay off when you start your "real" company 2, 5, 10 years from now where you won't be able to risk making dumb business mistakes you'd have learned if you were a landscaper for a year.
Don't quit your job and don't do anything relate to your workplace.
Small time businessman is sometimes just formalizing your paperwork and how you operate. You're not "a guy" who mows lawns or "a guy" who buys broken shit, fixes it, and resells it with a guarantee, you're a small businessman. You may grow that into a full time job for yourself, or even for a hundred other people, someday, just not today, not yet.
