If you're just starting out I want to reiterate a point for you that people have been reiterating to me from the beginning. In the big scheme of things I am also just starting out, but I'm hoping this will save you some heartache, possible delusions of grandeur and hopefully help you increase your odds of 'making it'.
If you're starting capital is:
Less than $1000 = Keep saving
$2000 = Keep saving.
$5000 = Keep saving.
$10,000 = You're getting there, don't lose hope.
$20,000 = Commissions won't be the end of you.
I hated hearing this when I first came to the markets, but one needs to hear it:
If you don't have enough money to approach this as a cut throat business, keep your money in the bank and LEARN before you lose your first lot of savings. Between commissions and just being a general noob and making mistakes, statistically you stand a very small chance of survival with small amounts of money! Note* even 20k isn't ideal, but it's more reasonable.
If you want to be a 'day trader' there are a lot of free simulators available so that you don't have to lose EXCESSIVE amounts of money learning, in what will inevitably be a steep learning curve.
Be patient and persistent.
Take it or leave it, just felt I should share it.
