For all of you performing (or interested in performing) mindfulness, I recommend you read this: The Honest Guide to Mindfulness : zen habits.
If you have been doing mindfulness for awhile and you are getting frustrated or giving up, then it can help ease your frustration and prevent you from quitting. If you are new to mindfulness and concerned you won’t be able to do it effectively, then it can help give you some perspective.
Mindfulness has been good for me. I am looking forward to reading this from time to time whenever I find it difficult.
