In my case, the problem isn't the level of intelligence of those around me (I am in a pretty good profession for it and live in a neighborhood full of professionals). My issues are my voracious appetite for books (for me and for kiddos) and my weird thirst for learning (instruments, languages, cooking, science, history, etc. etc. etc.). I do tend to minimize that a bit just so that I won't appear too odd to those around me and I share with those who share the same passions.

I have found a pretty cool website - Your Rainforest Mind by Paula Prober. It really appeals to me. You might want to check it out.
