The weekend is a 64-hour block of time you have to yourself. Many people spend the weekend mostly catching up on sleep and watching TV, but you should carve out a little portion to improve your life. You might do something for your health, like taking a long walk, or preparing some home-cooked meals for next week. You might do something for your mind by reading an inspiring book, working to improve your skill at a hobby, or meditating.
Take out your calendar and schedule a small block of time for self improvement. When you are done with the activity you scheduled, immediately schedule another block of time for next weekend. When you have just enjoyed the experience of spending time on something uplifting, you might even want schedule a little more time for next weekend.
