Since we are in the same boat, here is what i am doing before pulling that trigger:
1) Make sure you have enough capital to protect your family in case your rades make you bankrupt. Always, keep your family first.
2) Treat it as a business and not as a gambling. Have a well thought out plan before each day. Stick to it.
3) Dont over-trade. If I have three stop-losses for the day, I am out, no matter what my "ego" says.
4) Make sure atleast you know and have applied some of the technical analysis or charting stuff on real trades. Paper trades dont work and should not be used as a reason to quit your job.
5) Read about some of the awesome stuff floating around on this forum.
As for me, my company is about to be shut down and I am not looking out for a job. I have a wife and kid to support, and still I will be taking this up as a profession because trading for me is not about making money, its a passion. If you are passionate about your job, money would follow.
And yes......Trading does make you rich, only if there is no Gordon Gekko in you
