I used to love to untangle chains when I was a child. I had thin, busy fingers, and I never gave up. Perhaps there was a psychiatric component to my concentration but like much of my psychic damage, this worked to everyone's advantage.
The design of each element should be thought out in order to be easy to make and easy to repair.
Somewhere along the line, I realized that I liked telling stories, and I decided that I would try writing. Ten years later, I finally got a book published. It was hard. I had no skills. I knew nothing about the business of getting published. So I had to keep working at it.
