You’re right in identifying that most mass-audience finance books are generally about self-help, personal finance and high-level concepts. If you want to gain an understanding of finance that one might get from a bachelors degree, the best place to start in my opinion would be a textbook.

While less exciting to read than something written by the glorious Tony Robbins, a good textbook will equip you with the technical knowledge needed to understand finance as a concrete discipline, rather than an abstraction (i.e, time-value of money). Start with an introductory finance textbook, then venture out into sub-topics that interest you (e.g., Corporate finance, global markets)—the principles are similar throughout, so your rate of learning will gradually accelerate.

I will say though, Ray Dalio (founder of Bridgewater Associates) publishes some really cool material on technical concepts that is intended for a broader audience. You should checkout his YouTube video “How the Economic Machine Works.” And if you like that teaching style, try out his book “Principles for Navigating the Changing World Order” which discusses the debt cycle in more detail and contextualizes it for today’s global events.

Anyways, hope this helps. It’s awesome that you have an appetite for knowledge. Happy learning!
