A quote from Dr. Who:
I admit that there are times when I go to the Dark Side, choosing to see the worst case scenario in changing, disappointing or difficult situations. I work to keep that move to a minimum, to spend as little time in Mordor as possible. When I recognize that I'm there, when I discover the darkness clouding my mind and soul, I find something to smile about ~ some small thing ~ the sun shining, the beauty of the clouds, the sharpness of the air, anything that will provide the opportunity to change. The best thing is remaining the optimist!
What do you do to keep yourself in the ranks of hopers?
