Where to begin?

I consider myself an average joe investor. I know very basic things about the stock market and have worked my way back to even in my portfolio before the crash. I didn’t go to school for finance in fact I work in the legal industry. I love finance and especially stocks/investing. I started “learning” how to invest freshman year of college and historically I’ve profited instead of losing money but I want to start actually learning the market as well as all the different types of investments such as options and I want to learn all the basics so I can be more informed with what I’m doing. Where do I begin? Any help would be greatly appreciated.
