Don't quit your day job...because if your day job is tattooing your doing alright lol... my advice would that now you know you can tattoo professionally you should start to push out convention level pieces and get out of the comfort zone and see what your really made of... start moving in the direction you want to go, instead of letting walk-ins and magazines dictate your next tattoo.... grab a couple ghost white freaks and blast em up for cheap if you have to..
Because there is a saying that I live by.
