Since there is a lot of money to be made in this area and I think it is simpler to market our products online via social media than it is to do so physically offline, I would prefer to make money selling digital things.
Dropshipping sounds interesting, but I know little about it. Well, if I was going to make money, I might try employment sites cause it's how I made money before. Those sites made money from ads
Note: I did consider selling digital products such as music lesson access. However, it's incredibly tough to sell, even if you got good stuff.
