2. Being social and having a hobby: Having friends is important! A life without friendship is devoid of meaning and having friends who listen gives me fresh experiences and perspective that enhance the overall quality of my life.
3. Shut it down: When the marginal quality of my work diminishes, I take a break. The benefits of being refreshed vastly outweigh the cost of time lost. As a healthy and active individual, I do this all of the time.
