Celebrate the individual!
I can only tell you my thoughts from my growing years was that the feeling of not fitting in is a really hard thing to deal with, and my parents’ tendency when I was able to vocalize it was to say keep trying. The hardest job a parent has is getting in touch with a child's fears and questions about life.
Hindsight tells me that it was OK to not have lots of friends; there were other things that could have made me stronger. Celebrate the individual!
I have leaned a lot about human relations and self worth reading the autobiographies and biographies. The one you sent me on Feynman is a good example of someone who did not fit in, and how it affected his life.
Does any of this make sense? There is more, but I will let you tell me if you want to kick it around some more.
Hmmm, this letter was six handwritten pages and it only filled two typed pages, and I cheated at the margins at that.
Now I am listening to a jazz song featuring an alto sax. Boy, my playing does not sound like that at all.
Practice, practice.
