Dont waste TIME, its precious! 24 Hours | 1440 Minutes | 86400 Seconds of time we have in a day. Considering we spend an approx of 9 Hours a day on - sleeping + eating + other personal things, we are left with just 14 hours. Considering I am an MBA i.e. I am required to work for 10 Hours (9 hours is average time you spend in office/work place). I am left with 4 hours.
