I just don't like writing about myself - why should my personal experience be of interest to anyone else? It's safer to write about what can be reasonably expected to be a shared experience. I guess one of the things I'm wary of is getting feedback that my writing is narcissistic because I'd be writing about stuff which is primarily interesting because it's about me.

Interestingly, I don't think other people's personal writing is narcissistic and almost always recommend it.

A vivid image of what should exist acts as a surrogate for reality. Pursuit of the image then prevents pursuit of the reality -- John K. Galbraith
