I dont nothing about business. Like if i manage to get a great idea and start to make money, i have no idea how to manage employees or the company itself.

What topic should i study? finance? business?

For example when i saw that reality show sharktank, where entrepreneur has their idea and already a running company but wants a boost and they start to talk, i don’t understand a thing and probably i cannot reach a good level cause of my lack of knowledge in that field

For example elon musk studied economics.

What topic should i study to will be able to manage a startup and a company and make business?
