You have to run your business. I recommend business in the food industry and also hairstyling. Doesn't matter what we invent, we want to eat delicious foods. Small supermarkets, and small restaurants, are very profitable businesses locally.
I also recommend hair salons. At the moment there isn't any AI that can cut your hair. Being a barber or having a hair salon business is a safe bet in 21st century to my min.
Starting a business in the midst of economic hardship like today is just suicide. You can see so many businesses closing down these days because of the recession. Not to mention that starting a business requires capital - and spending a lot of money during a recession is not a wise thing to do - and there is no guarantee that you will get customers when you spend that much money. So it is a difficult situation and it is not easy to say that because we have not experienced it.
