My friend George's grandfather was fond of saying that the hardest part of exercising was putting on your sneakers. I'm still working on the exercise bit, but I'm also aware that the same principle goes for any kind of work.
If I just sit down and start something it amazes me how easy it is to get into a flow state within a matter of minutes. Then minutes become hours, and those hours become satisfying in ways that otherwise don't happen. I don't care if you ever read what I wrote. I just had the best time writing it. The process was it's own reward.
I'd like to cultivate a habit of starting. I know that sometimes it's good to finish things, but you can't finish what you don't start, and if you keep at it, some of the things that you start get finished. I remember when my first CD came out. It had taken 18 months from start to finish, and most of the songs had been written years before production even started. But I had put off beginning the production for a variety of reasons and for a long time. Once it was begun it took on a life and momentum of its own. While it took a long time to finish, those hours, days and months didn't pass slowly.
Just start. Anything. See where it takes you...
