I was too young to fully understand why, but as I got older and looked back on those years, it became clear: I identified with Spock because he was weird, and cerebral, and he was different from everyone else. He was just like me, but the things that made me a target of ridicule on the playground made him a valuable and vital member of his ship's crew. In ways that I couldn't articulate at the time, I wanted to be Mister Spock because if I was, I could be myself –quiet, bookish, alien to the people around me — and it wouldn't be weird. It would be awesome.

The whole thing is here and it is quite lovely.
