Can I recommend both one up on Wall Street, and beating the Street both by Peter Lynch (the guy in my avatar 
) really fantastic and inspiring reads.
He worked in fund management for fidelity for many years and he shares a lot of his insights, he was extremely successful in his management of the flagship Magellan fund, beating the market consistently over the 13 year period.
What I really like the most about the books is he shares successful investing strategies but also relates it completely to a retail investor who doesn’t have the tools and constraints a fund manager has.
