Where Does Your Time Go

We all say "we don't have time" to do something and we have all experienced having too much to do and not enough time.  This last week, I mentioned to hubby that we never have time to do fun things anymore.  Then I started wondering where does all of my time go?  In a 7 day week there are 168 hours, so I decided to see how I spent my time.  I was able to account for 122 hours:  work/school takes about 70 hours per week, sleeping accounts for 42 hours, and my commute to and from work is about 10 hours.  That leaves 46 hours per week/6.5 hours per day to do items around the house, relax, and have fun.  That should be more than enough time to relax and have fun.  So why don't I ever feel like I have enough time?
