Seriously don't agree with floor 888. When a person goes to a very high level, he needs to find at least a similar person whom he can exchange ideas and experience with, because most of the time, people from different cultures, different backgroundshave different understandings about the same things. Their skills are not totally overlaped with each other. When one can have a similar expert who is willing to showhis experience and skills, he is very well blessed, and he is expected to jump to anew higher level.
