In addition to taking economics, accounting, and law classes, I really learned a lot from reading public corporation's proxy statements. I would literally spend hours reading through Disney's annual proxy statements. You can find them on the corporations' site usually or as an SEC EDGAR filing. I also learned quite a bit from going through SEC filings http://www.sec.gov/edgar.shtml http://www.sec.gov/edgar.shtml of companies I admire (Google, Disney, etc). I also just looked at public stocks (finance.google.com) and tried to figure out what everything meant (EPS, P/E ratio, ROE [return on equity], etc). Reading articles in the Wall Street Journal also taught me a lot.
