I can fail at sports and that doesn't bother me with most sports.
This is my problem, which may sound like gloating but it isn't.
1) I have passed every grading I have taken at Karate in the last 5 years.
2) I have never failed to achieve/beat my target grades at school.
3) I'm a natural goody-two-shoes. Therefore I have no problems with any authorities, e.g. Parents, School, Police, etc, etc.
I have very little exposure to failure and therefore I am vulnerable to it when it does happen. This also means that I often (roughly 60% of the time) have to assure myself of a high chance of success (roughly 70% as a minimum) whenever I attempt something.
I also have problems with dissapointing people. This doesn't help when my father has told me himself that he is a perfectionist, although he's beginning to mellow out a bit (I blame age and Warcraft).
EDIT: The flying bus was great too. The creatures made a good "enemy" though. I don't think there can be a better show that is quintessentially British.
