Are you getting enough sleep? How much is enough?
When a person is disciplined in one area, it often translates to other parts of life. Discipline in exercise often results in healthier eating choices. Who wants to chase a hard workout with a donut? The same goes with disciplined sleep. I’ve never seen a truly disciplined person who had lazy sleep habits. Some people sleep too much, while others don’t get enough sleep. But the disciplined sleeper sees the benefit of good rest and strikes a healthy balance between work and rest.
