I highly doubt that anyone seeking a less cluttered life is someone who finds way too much time on their hands. So where is all your time going?
Put a piece of paper up where you'll keep seeing it (on the fridge is a good spot) and all week write down where your time goes. "90 minutes reading blogs", "30 minutes cooking dinner", "110 minutes commuting", "8 hours working", "20 minutes lunch", etc.
At the end of the week, compare what you did to what you wish you were doing. What's the biggest chunk of time invested for the least payoff? What could be completely or mostly eliminated and replaced with something more important to you?
