Scott Adams (yes, from Dilbert) hit it on the head with his blog post today, titled Rounders Vs. Accumulators.
ROUNDERS: This group rounds things off. A problem that's a two on a scale of one to ten gets rounded to zero. If a rounder has five problems that are all about a two on a scale of one to ten, he'll tell you he has no problems.
ACCUMULATORS: Accumulators add up all the little problems until they equal one big problem. If an accumulator has five problems that are each a two on a scale of one to ten, that feels like having one problem that's a ten.
Rounders are generally happy, because they perceive their lives to be mostly problem-free. Accumulators are often miserable because "nothing is going right."
I try to be a rounder, but sometimes I find myself accumulating.
