I became a global multi-strategy hedge fund manager at 23 ($1bn fund) via a series of odd events so didn't have time to go through the classic CFA analyst => fund manager process.
I get asked this question a lot and usually recommend http://www.realvisiontv.com these days, particularly if you like videos.
Some variable quality, but some really excellent, unique viewpoints from value investors and macro managers there.
I would also recommend the Market Wizards series by Schwager and Inside the House of Money/the Invisible Hands by the Drobnys.
