Writer's Block

I feel I have to walk around with my computer around my neck
these days. I have this brilliant topic to write about and then it
slips from my mind the moment I get to my computer to write
about it. I do carry around a notebook but the trouble is the same
thing happens the moment I open the pages the topic slips or as
the case maybe I have the habit of carrying around a notebook
but often there is no pen. As a photographer I manage to carry
around my camera and manage to capture the photos I want but
I never manage to capture my ideas on paper. Well I suppose it
happens to everyone and not just me. Let's hope so anyway.
Perhaps I was a born photographer but I was never supposed
to be a writer.
