I don't know who that guy is but my small and very limited in scope (a particular sport) and radius (regional level) experience with fame made me wary for life of ever being famous and I don't really understand why people would seek that.

Just the fact that complete strangers were recognizing me and chatting to me like I was their best friend while I had no clue who they were was a really uncomfortable feeling. It was one of the multiple reasons I didn't tried to be a professional in this sport.
