If I trade, I would save enough to 160K, put all in an account, and trade only with 40K (80K with margin), the other 120K saved in a second account. I would fast trade with the 40K account, and when the time is right, I will know when it's right, use the other 120K to buy and hold for intermediate terms. The cash cow will be the 120K account, whereas the 40K fast trading is what to keep in touch with the market's hearbeat, and develop my "instinct" to know when those times come. I believe there are occasionals where you could jump in and make more money than you can make trading everyday. Maybe ten times a year could easily equate your hard work everyday. But you do need to keep in touch everyday by trading.
I would keep my day job to pay bills, and have a decent life, saving all equity for strictly trading . Probably a second shift job. When I trade, somehow I just want to keep all the cash to have trading power. It's weird, but I guess everybody else might have the same mentality.
