What sort of expectations do you have? Are you a person who thinks we should be expectation free so as to avoid disappointment? Or do you see expectations similar to goals: ideas that provide forward movement and something to strive for?
I fall in the later camp and tend to agree with Sam Walton when he said, "High expectations are the key to everything." I can't help it; I expect a lot. I'm not sure how I would ever go about changing that.
