That's exhilarating if you're doing well, and very crushing if you're not.

And some of the reason for that is that people take what happens to them extremely personally -- they own their success, but they also own their failure.

The defining characteristic of pessimists is that they tend to believe bad events will last a long time, will undermine everything they do, and are their own fault.
