The most important thing you must consider before actually quitting your dayjob to do this full time whether the manner in which you've made your profits will continue to be viable in the future. No doubt that this is a hazard that every trader faces no matter how long he has been trading, but since you've only been doing it for a year or so you need to be extra careful.
Were the majority of your profits on the long side, given the bull market this year, or did you have a good split between long and short? Were they concentrated in a certain sector that has been trending -- energy, metals etc? Or were your trades spread out over a variety of non-correlated sectors? Do you suffer relatively large losses on a small number of losing trades, while having a high win % overall? Do you already employ strict money management rules, or are you "flexible" with open losses?
Just a bunch of questions off the top of my head, as the real question isn't about absolute or percentage return but quality of the numbers.
