On What I Vow

With the passing of the summer to darker, more dramatic, gloomier days (even in LA), I have made a promise to myself. I will take a daily walk.  I know this sounds like something my elders would do, but I think of my walks as meditation.  Each and every day, despite the weather, what I have on my plate, and the physical activity that I have already mustered, I will walk.  I will put away my computer and my Iphone and go out into the city and just walk around. 
What's your daily promise to yourself?
