I agree, I have been in the position of working with photographers for my entire career - 2016 makes it 40 years.
Over these years one can imagine the numbers that I have met. quite frankly there are many untold , unheard bodies of work out there that will never see the light of day.
IMO the biggest barrier is finances- as it is really difficult to keep one afloat day to day, as well be creative and make work for others to see and navigating the world of the gallery's.
I think Vivian did what she could and I do not find her lifestyle to be that quirky , but one of an artist obsessed with capturing her surroundings.
I keep thinking about The Christmas Carol - where Scrooge would work every day... sometimes I feel like that as I am in my lab every single day except Christmas, this year I
went in Boxing day.
I always ask my wife if its okay with her that I spend every single day working on images. Many would describe me as a workaholic crazy or a nut job for being like this, I basically
think I fell in love with photography, and there is a burning desire to continue imaging. I am obsessed with what I do for a living but as well as a creative outlet .
Obviously Vivian had that desire and I can assure everyone here there are thousands of people pursuing photography that fall into this description.
It is amazing what people will project onto others.
So far as I know, there is a bit of anecdotal evidence from a few people who met her that she wasn't straightforward and could be a bit off-key or difficult sometimes.
How we get from that to being "dysfunctional" (whatever that means ) or being plagued with "inner demons" I have no idea.
Sigh ...
