Plus, fog is just cooler than rain

A perfect quote for our practice from "Zen Mind, Beginner's Mind"

After you have been practicing for a while, you will realize that it is not possible to make rapid, extraordinary progress. Even though you try very hard, the progress you make is always little by little. It is not like going out in a shower in which you know when you get wet. In a fog, you do not know you are getting wet, but as you keep walking you get wet little by little. If your mind has ideas of progress, you may say, "Oh, this pace is terrible!" But actually it is not. When you get wet in a fog, it is very difficult to dry yourself. So there is no need to worry about progress. It is like studying a foreign language; you cannot do it all of a sudden, but by repeating it over and over you will master it. This is the Soto way of practice. We can say either we make progress little by little, or that we do not even expect to make progress. Just to be sincere and make our full effort in each moment is enough.
