Each hour you spend is a piece of your life that once spent, cannot be replaced. It is gone forever. Spend your time on those things that matter most to you. Remember, nobody on their deathbed wishes they had spent more time at the office. Taking ten minutes at the end of each hour to straighten up whatever has accumulated during that hour, saves endless hours of searching for lost things among the piles of stuff.
Time is democratic.
We all have exactly the same amount every day. We are wherever we are in our lives right now as a result of all the choices we have made up to this time. We will be wherever we will be in our lives ten years from now as a result of how we choose to spend our time between now and then. Every material thing we have, takes time to find, maintain, put away again, etc. Clear the clutter and you clear your mind and your time.
