A man is never too busy to admit how busy he is. Sitting in front of a computer or being glued to a handheld device isn't akin to enhancing productivity. The best way to enhance productivity is to take occasional break from work and connect with your social and natural surrounding. Best learning as an entrepreneur happens outside your office or room.

In a nut shell, you need not plan your day but just plan your working hour each day. Anything outside work should be kept unplanned to make most out of the day.
