All business is good if you can do it properly. So you need to gather some experience and knowledge to run a business.
This is information era. So everyone needs information in some different aspect. So if you can help them by providing some information or works which is related to your field then you will get paid for that. This is called consultancy business. I think this is the best to start because you don’t need so much money.
Also, you can help people for free so you will get more followers and once you get a good number of followers then you can share someone’s business to your circle and get paid for that. This is another way.
