Your long-term goal is to make sure your full-time gig involves work you’d do even if you weren’t getting paid—work that consumes your mind at all hours of the day. In the meantime, you have to be more efficient about how much time you spend working so as not to appear a workaholic. I can’t say that you have an unhealthy love for work—it’s just what you enjoy doing, this whole writing thing. When people ask you what you do for fun, you should say this. That’s not to say you should do nothing else, but this shouldn’t be too much of a burden.
However, I never want you to remove the label of work from what you call your writing hobby. To turn it into a full-time venture, later on, you have to treat yourself and act like a professional. Hold yourself to deadlines. Manage your projects like you would have to if you did this for a living. Don’t restrict yourself, of course, but don’t let yourself become a starving artist because you don’t have the discipline to hone your craft day in and day out. This is your job, whether you get paid to do it or not.
