1) Amazon.com and start reading.
2) get a brokerage account but DO NOT trade. Just watch and try to understand what you are looking at based on your readings and research.
3) Once you can come up with a resemblance of a plan that fits your personality, paper trade it for a year. In a sense, take ownership of it.
After that, you will know what/who else you might need, or determine this is not for you.
Final confirmation comes with you turn live.
All is all, be PROACTIVE.
The other route (main stream), get a MBA/(Quant MS/PhD) from a top school, and then apply to join a firm. They will train you to trade THEIR money, THEIR way, with SOMEONE breathing down your neck, but a FAT paycheck at the end.
you pick based on your personality.
good luck.
