Bad mood!

Many a bad mood is down to one thing: discontented attitude - pawning what’s readily available for a mere yearning, even if it seems certain to happen. The feeling's a toxin and it has an antitoxin: an attitude of gratitude for what’s readily available. So you can complain about the food being unpleasantly cold, or rejoice because there’s food, and in knowing that it’s easier to warm the food.
