Or, if you're feeling particularly adventurous, head on over to Overachieving: The Delusion of Thinking You're Better to see how the opposite end of the spectrum looks like.
Or, if you just want to wallow in the misery of underestimation, check out our Exercises in Underestimation for some good old-fashioned self-pity.
