One of the ways to keep a positive attitude is to keep busy. Whether it's writing or cleaning the house it doesn't really matter. Anything that keeps you from falling into the pit of dispair is helpful.
One thing I'm working on is my pond. I have the goal in mind to create a zone of zen, so to speak, a place I can look to with a sense of pride and satisfaction. Your choice may differ but that's okay because all that matters is that you have something to keep you going.
KEEP BUSY!
