Short idea (168): You can make two columns — one for all the things in life that are fun and one for all the things in life that are just work. For many people, as you get older and older, activities that were in the first column when you were younger have to be moved over to the second column. Towards the end of life, activities that were fun or so easy that they were barely noticed, like breathing or walking, can become labor and even labored.
