But don't worry too much about that. This is not a race. You are not in competition with anybody, and there is no schedule. One of the most difficult things to learn is that mindfulness is not dependent on any emotional or mental state. We have certain images of meditation.
Meditation is something done in quiet caves by tranquil people who move slowly.
Those are training conditions. They are set up to foster concentration and to learn the skill of mindfulness. Once you have learned that skill, however, you can dispense with the training restrictions, and you should. You don't need to move at a snail's pace to be mindful. You don't even need to be calm.
