I have many friends who write, far fewer that can afford to write full-time. And that's okay. It has to be. For we writers are not only creative thinkers, we are real life livers.
That means that we don't give up even when we know we can only spare a part-time career in writing; at least for now.
We may write at 10 p.m. or 2 a.m., but we write because we can't not write.
Yes, we may dream of the day when, Lord willing, we can drop our full-time job away from home and write, but until then, we keep writing and dreaming.
We don't stop because the stuff of life is difficult and doesn't allow us to do what we - want. We're not little children after all who need to be catered to their every whim. We're adults, and although many people say we have a certain 'childlike' quality (we couldn't really write if we didn't) this child knows better than to complain about his/her sorry life in favor of doing all they can to make their life work, the way it is - right now.
Living in the moment is important, probably even more important than dreaming of the future, because right now at this very moment something tangible can be done.
