Human beings need some idle time now and again to put things in perspective. To slow down. To take a moment to be curious as to the state of ourselves and the world around us. Procrastination may not be all that bad.
Why do you work and when you do, how do you work? We think we are rational beings but we are not. Our belief system has a strong influence on our life. If we want 4-hour workweeks or 7-day weekends, we need to change our beliefs.
