I am looking for an online resource to learn finances/economics/investment from the ground up.

I am using those three words because I do not know the difference quite well. The bottom line is that I want to learn how money works, and stop "selling my time for money" (working for some employer). Maybe starting a business, investing in real state, or stock market, maybe another route that I don't even see...

• I am looking for content ideally free, but good material deserves to be paid too.
• Progressive complexity starting from little or no assumptions: several youtubers have all-over-the-place topics that they comment on, assuming you know what they are talking about.
• Perhaps a book or series of books is the solution to this? Or an online course? But you know, every "money bro" says they have the best book/course ever.

thanks for your comments :)
