@ joelwy, Its always good to keep a job until you have established a very hefty cushion..Once you'll be sitting on a few hundred thousand dollars and debt free..then you can start thinking of trading full time..that's my personal opinion of course..but I am married and have 2 kids..so you're hearing this advice from a father here
If you are of course without resposibilities like mine..you might be having less to lose and be able ot take more risks..Also, if you are younger than I am, its always easier to find another job if the market lets you down one day..
I prefer keeping my job until I completely finished paying my mortgage and all my loans...and have that couple hundred grand cushion ..then ..I'll retire and only trade for a living !! YAY! I cannot wait until that day arrives..
