Do not measure thyself!
In my work as a psychotherapist I often see individuals who are plagued by a relentless measuring of themselves. These people carry on an internal dialogue whereby their critical voice is enslaving; judging and measuring most aspects of their lives. In such circumstances, these people rarely get to be present. Even when in conversation with others, they are only partly there; for a more private aspect is carrying on a self-critique at the same time.
