Trust your instincts on this one, especially before you begin acquiring wife/house/kids, etc., as this will chain you to the biggest paycheck. I have worked in several large corporations and in general they stifle creativity and are so mired in politics that it is nigh impossible to accomplish anything of substance. The key here is that you highlighted practicing your craft as creating and being rewarding. For most corporate devs, it is only a job and they do belong and thrive there. For you and others like you, find a smaller place (or a startup that you can turn into a bigger place) that needs and recognizes the fine art that you practice.
