I sometimes come across folk who make their living as writers. What I've noticed is that the good writers are nearly all nice people and very easy to talk to. I don't know if we've got a chicken and egg situation here. Are they easy to talk to because they are good at their job and comfortable with themselves? Or are they good writers because they are basically amiable people who have little problem making a connection with readers? Sadly, the converse is also true. The snottiest and most unpleasant "writers" I come across are usually also pretty bad at what they do. Perhaps even in their arrogance they still  have an uneasy awareness at the back of what passes for their minds that they are actually talentless. That's why they stand on their pretentious dignity so much and go into such a snit if they feel they are not being shown the respect they somehow feel they deserve. Many of them struggle to even reach the giddy heights of mediocrity.
