I can only give you my opinion as it would apply to me. If I didn't HAVE to work, you can bet your sweet bibpee I wouldn't. But...on the other hand, if you feel that you have a need to work, or want to, then structure you writing time to gain the most from it. Like what is your peak time for writing? Are you fresher in the mornings or evenings? If it's mornings, for instance, then set aside whatever you can spare in the morning time to do nothing but write. Treat it like you would any other job and DO NOT let anything else interrupt that writing time.

If it's evenings, do the same thing. By structuring your time, you are writing consistently, and not taking anything away from your family, or your new job.

Personally, if I were in your shoes and didn't have to work, pigs would fly before I would take a job outside the home. I would be a writing fool if I had the time.
