Novembers have been establishing to me that I really do have the capability to write, and write on demand, and write reasonably well. I can take a thread of airy nothing and transform it into a first draft of a book. Granted, there will be yowling and thumping and perhaps even tears on the way (I don't tend to cry half so much anymore, so it's not a given) but I can sit down and come out with written material.
This is something that I can do in my current position. It's not the job of my dreams, but it's close to home and it's flexible and I'm comfortable there. If I really need to, I can go down to part-time. I can go back on the phones if I want to.
Any new investment of time that a different job takes is that much time that I don't have available to me to write. This job that I'm in now is a pretty decent day job.
