A lot of people forget how taking a walk in nice weather alone is a very uplifting. It gets the serotonin working, and it's not super taxing. It puts life in perspective. You see things passing by and the majesty and timelessness of world. And it's totally free. Taking a book or a CD player or reading or writing for few hours is really taking nice care of yourself. When you're in a relationship you don't get around to doing that.
