If you're going to be a writer, you're going to write because you have to. It's not like other arts and not nearly as rewarding because it's a lot lonelier, and most of the time it's just you alone in a dark room or a coffee shop. But a lot of writers have to write because they're writing for themselves, so whether or not someone sees your work or not- they're still writing because they absolutely have to.
Have a deputy and develop a successor. Don't be consumed by the job or you'll risk losing your balance. Keep your mooring lines to the outside world - family, friends, neighbors, people out of government, and people who may not agree with you.
