I think artists are driven by the need to have Mom put the little drawing they made on the refrigerator with those little magnets.
I'm not sure what motivates writers. Humans have a long history of needing to tell a story. It comes naturally. When I was a kid I wrote little poems. English class was my favorite subject. The teachers would tell us to write something.
With some of my heart I want to write. Some of my heart because I have to divvy out my heart. I started to learn guitar in eighth grade. Soon that was all my heart.
Life gets in the way of childhood dreams. These dreams don't manifest themselves in reality. Dreams don't pay bills and raise children.
I've written songs (many), stories, novels, plays and musicals. I bring this up because when you try to find an agent it's "List your published work." This is where I make the Lucy face(I Love Lucy) and go "Ew-illll huh-oh."
I've already dealt with "You want to show your paintings here? Really! We do art here!"
So "We are sorry to say no." is not new territory for me.
