He occasionally shares things but only when they are directly related to something I have said. The most personal one was that he had bumped into his former boss who was a big reason he left his last job and managed to have a cordial conversation even though he doesn't like her very much. In the context of our relationship it seemed like a really personal thing for him to tell me.
Most of what I know about him comes from his book, his website, his amazon bio and an online interview I found of him.

I much prefer it this way though, the over disclosure from T1 was damaging.
