Hours in a day

How come there are never enough hours in the day?
We got a lot done. It has been nice to have my mom here because it is another pair of hands (in fact we were early to church and I couldn't figure out why until I realized that she had cleaned up breakfast while Jim and I were getting everyone dressed).
But, there is always more that could be done.
Somehow I doubt that even with another couple of extra hours thrown in there that I would
1) have any short "to-do" list.
2) go to bed any earlier.
3) have a cleaner house or more of my work done or "find" time to exercise/to a hobby/insert any other activity that is easy to make excuses for why other things are more important.
