Not that experienced with business, but I would recommend that you should get a stable job with income that is coming in reliably. Create courses on your knowledge and promote it as much as you can on sites where people actively look for certain skills such as Udemy, skillshare, etc. Then I would say have a side hustle service-based business that works around your job schedule and has a low start up and makes decent money. If you already have a car, this may not be the best option because of gas prices, but Uber is something that you can work throughout the night because there are workers that need transportation during these times. I’m getting into window cleaning because the start up isn’t too bad either. That way you have 3 different streams of income that can be made with 1 being a stream one where you don’t have to be there physically. When you need it, money will come if you work hard.
