Read all the Market Wizard books and see which trader's style appeals most to you. Start there and see where it takes you. Good journey to you.
Two of my fav's in addition to Market Wizards mentioned above: - Reminiscences of a Stock Operator by Edwin Lefevre (1923) - Speculation as a Fine Art by Dickson G. Watts (1965)
Honestly consider psychology/discipline books like Trading in the Zone by Mark Douglas. Never underestimate the power of attitude when trading.
Search the internet for information on why traders fail; some claim that over 90% manage to do that; then don't do any of that stuff. Take the time to develop a well thought out trading plan, and follow the plan. You can't buy trading success; everything you need to know you can find online.
Try Al Brooks' stuff if you're intent on day-trading. Great thoughts, though badly written down. His video clips are somewhat more accessible.
