Some people do not wish to admit that others' accomplishments are the result of study and hard work and try to absolve their own lack of effort with the "guru delusion." It's easier to dismiss the truth than to admit that the level of effort put forth by the "guru" is what has made the difference.

Yes, this is a generalization. No, I'm not dismissing talent and intelligence. I've seen this behavior many times, I've even been guilty of it myself in the past. Perhaps that's why I understand it.
