Why aren't I writing?

I met with a writing client today who is revising a terrific memoir but has trouble getting to her desk:

"I'll do anything but write," she told me. "I'll clean the trim on the stove and scrub toilets before I'll sit down and get to work. But once I do, I feel great, whole, happy."

Why don't we write when we know it's what brings us the most satisfaction? I, for one, tend to be a deadline-driven writer. On assignment, I get the job done and in a timely manner. As for my own work, well . . .I have been known to wander down many a tantalizing path before I get started in the morning.

Here's an essay on the subject from Glimmertrain.
