Why are some people afraid to be judged by society regarding only some things?

Ehh, that's a really good question. I think for someone to really handle being famous they have to:

be eccentric
enjoy being the center of attention
be drawn to a fast-paced/intense lifestyle
be incredibly hard workers
be very sociable

Then again, there are probably relatively normal people who adapt to being famous without having all of these traits. I think to be any kind of high-level achiever you have to be pretty eccentric though, especially in show business. There are probably plenty of people too who are exceptions to all of these and maybe truly don't like being famous. I think it's a very weird thing for a human to be as well known as, let's say, the likes of Brad Pitt or Leonardo DiCaprio or Meryl Streep and it's not surprising that some of these celebrities are so out there.

I would say that they also have to know how to take criticism and don't fall under social pressure. As you said, there might be exceptions to the rule.
