A decision to wax "Pollyanna", for the sake of my battered psyche

It's no secret that I've been having a rough fall, but I'm tired of being negative, so I've decided to focus on the good things, instead. These things include:

• An excellent Thanksgiving holiday, full of food, family, and fun
• A husband who is the perfect match for me, who keeps me balanced and sane and laughing
  
• A job I like that apparently likes me back
• Research ideas that look like they're going to make a killer dissertation
• A professor-mentor who is a stellar example for a TA like myself
• The continued good health of friends and family members
• A cozy, comfy, cool old house that is truly a home
• Excellent musical colleagues
• The light at the end of the tunnel

And so on these things I shall ponder, to avoid sinking into the Slough of Despair. Why is it that the bad bits of life always seem to affect one more than the good bits? I think that's highly unfair to the good bits, and so I am hereby reversing the trend. Wish me luck with that, won't you?
