This is a question of balance. Those who come to me and say, “You know, I work 15 hours a day,” I say, “I am not interested.” I am interested in the quality of working hours, not the quantity. The brain of the human being. Do you think that during the first five hours of the day you are the same as you are in the last five hours? No way. You’re tired, and if you’re tired, you stop listening, and the decisions you make are risky.
A good read and a good reminder.
