As an antidote to too much seriousness, we need playfulness and spontaneity. Hobby over duty. Entertainment over commitment. Relaxation over dedication. Try to be playful at work or at home at least once a day. Try to make your partner, friend, or coworker laugh. Take a detour on your way home. Jump in a puddle. Go for a swim. Get wet; get dirty. Be like a little kid once in a while.
