I will disagree vehemently. Wynton could blow the socks off of Bill Fielder, but the relationship was good for both. People in the know don't have to TEACH you new things. They offer insight into your playing, they act as a mirror reflecting what you are doing. They have another angle of looking at what you have achieved. They can challenge concepts, comfort when things aren't going as well as we would like, offer an outside but still trusted opinion. A husband and wife run out of things to "teach" each other, but the relationship still can grow. It is no different with a mentor. You guys that criticize this have NO IDEA WHAT YOU ARE MISSING. It makes me sick that these special relationships are reduced to throw away when I am better than you.
