What do you consider to be the best guide when it comes to investing and managing money?

This isn't me asking for financial advice directly but I just really needed an answer to this question because my high school Econ teacher kept recommending this show called Wealthtrack with Consuelo Mack. But the problem is that we don't use cable at home. We mainly use streaming services. So I can't watch the show. That show has made him more money with his money than anything and now it sucks that I can't access it.

So what is your go to show or app for financial guidance on what to invest in, sell, or do in the market to make money?
