Thanks to all who have answered so far. I've been reading posts here for about a month and I know it's pretty easy to just hear what you want to hear, and this would be a fundamental mistake for someone who wants to approach trading as full time, serious business, and I do.
I'm still working on the "financial house" to have enough funds to start the business, including a nest egg for about 6 months of living expenses, which I'm told is a very good idea, for surviving the learning curve.
As far as my aptitude and discipline for trading are concerned, I feel I'm in pretty good shape. I have been in a straight commission sales job for eight years and made a decent high five figure income. I was promoted four years ago and now manage the sales department for our company and am salaried at about the same level, but have grown somewhat tired of what I do and feel too limited in my earning potential. I am even considering going back to a straight sales job because of the limitations, both physically and monetarily of the staff position.
I have traded stocks since 1997, starting with Schwab Online at an astounding $29.95/trip! that's $60 before any profits realized. I was only playing "part time", was seriously under-funded, uneducated and just plain dumb. It took about a year to lose 7K of my 13K account. Switched to Datek, learned a little more, cut my commission expenses dramatically and have traded with marginal success until late last year when I believe due to my trading only part time, I lost another 2k on a few shares of CSCO and INTC.
It is obvious to me that all of my losses, since my initial learning curve have been due to only "playing" stock trader. If I could have watched my positions and gotten out at a disciplined stop loss level, I could have done much better. I haven't traded since last year and will wait until I can go "full time" as a business.
I read, watch the markets, play trade with Cyber simulator

and strategize for the time when I can make my living trading stocks, like so many of you have already done. I am patient and will wait until my financial situation is not a major roadblock and when I dive in, I will jump off the high dive into the deep end and not just dip my toe in, which can lead to the wrong idea of how cold the water is.
Thanks again for the replies and I look forward to hearing many more.
P.S. I forgot to mention that I LOVE the market and have a passion for it. It's the most challenging, interesting and difficult thing I've ever seen in my 38 years!
