It is always a temptation for me to stay home when it is cold and dark, to miss yoga class (when I am student, not teacher), to do my own practice and read and cook and play with the cat, rather than to be more engaged with all that is outside — friends, group yoga, and all the offerings of the city. I am always happier, though, for having gone out. Home is much more pleasing after an interlude with the outside. And if I dress right, it is even enjoyable to walk out in the cold, dark, rain, and say hello to all the dog walkers.
