One morning I was taking the train from Brooklyn into Manhattan, where I got the ferry to go out to Staten Island, and I was getting off the train at Whitehall Street, stepping off the train and on to the platform, and this thought came into my head, “You could decide today to be happy. You could just make a decision, instead of going in fear and trembling into the classroom.” Now it’s easy to say that, and it doesn’t always work, but I realized that I was resisting some kind of gloom, gravity, that most of us, most of the time, we look on the dark side, I think, but you have to work at lifting yourself up but I tried it that day. It was the beginning of that kind of practice.
