Not enough time

There just doesn't seem to be enough time in the day to get everything done! My 13 year old son was sick all of last week, so I didn't get to run a lot of errands. So, today I went to 4 different stores to try and catch up, but I still need to go to a couple of more! I just ran out of time because my 3 year old needed to eat lunch and take a nap before it was time to pick the other 2 kids up from school. In the meantime, I have lots of email, coupons, store sales(fliers), price updates, laundry, dinner, violin lessons, etc. to do. I try to do a little bit of each thing every day, but I never seem to catch up. Do any of you ever feel this way too?
