Never mind, upon closer inspection I get none of these stories. I suppose this itself is pretty 'Zen' (or at least ironic) given that my entire product line is made up of names suffixed -Zen...
1. Don't worry so much, and don't let everything get to you. Most of it is inconsequential and out of your control anyway.
2. Be deliberate. Think about everything you do while you're doing it. That is to say, don't let your mind be on auto-pilot.
I think a lot of people try to force the idea of zen to be much deeper than it is, they spend all this time searching for some deep meaning, when it neither exists nor is the point or aim.
