I'm pretty sure the world would burst into flame if you succeeded in breaking one of the fundamental laws of the universe. Kind of surprised it didn't when my INFP friend became a game programmer, really. :P
Really, though, don't worry about your MBTI here. Worry about finding resources for novelists and seeing how you take to them (there's probably plenty about finishing and tying up loose ends) and if it's a long-term goal you think you can stick to. Read up on what it takes to get published and the subject of writing as work in general.
