I recently found that using 10 minutes too work on a group of tasks will not only help you get multiple things done but it will help you reach several small goals per day.
For example wash 25% of your dishes or organize a small area in your home for 10 minutes. There is a lot of small things you can tackle each day even if 10 minutes is all you have. Set a small list and give each 10 minutes then start again until that list is completed. Plus the small intervals keep you from getting bored and leaving the task unaccomplished.
