Life is short.
School and work are important, but attending in a balanced fashion to other matters (physical health, spiritual wellbeing, family and social connectedness, etc.) are equally important.
As a practicing clinician, Dr. King has received immeasurable benefit from utilizing the same self-care skills he teaches clients. Prior periods of inadequate balance between work and self-care were, in hindsight, regrettable.
Thus, Dr. King encourages students and others to prioritize their own self-care skills practice as well.
