Money is everywhere

In life money is actually everywhere. You can start a salon and make money, you can start be a mechanic and make money, you can do anything and make money.

Economy works in this manner, people have this X amount of money to spend and they find infinite ways to spend them. You just to need to capitalize on this simple fact and just convince those people to spend some of that x amount on you.

It's better if you provide essential services, like food, clothes, shelter, etc. because human survival depends on that. However, even if you provide very niche services like toe tickling, you will always find customers who are willing to give your their money because it brings them happiness.

As long as you are able to illicit an emotion, people will just give you that money. That's why streamers, and movie stars are held to such high regard. They are able to connect with the audience at an emotional level and not only do they bring them small spurts of joy but they also become their idols/figures that they trust. Organizations recognize that and then they sponsor the individuals because they know the audience will blindly buy anything that these guys promote.
