If you're like me, the responsibilities and the to-do lists never end. Even when I reach the end of one list, there's always something else I could be doing. Like getting a jump on the next to-do list.
But the chores will never end. So it's important to throw the list out the window every now and then. Or add to it something fun. Something that has no purpose other than pure amusement or relaxation. A day at the beach, or a museum, or a talk with a friend. Skiing, or playing that video game, or just curling up with a book you want to but don't have to read. A movie, a walk in nature--whatever it is, it's time.
I've never believed that life must be all drudgery and work. Even the proverbial ant should get to be a grasshopper now and then.
