Mistakes are the portals of discovery.
Love the quote!
Artists and creative types will relate to the quote for sure.
When I've worked on creating jewelry or sewing, often a mistake brought on the discovery of a new technique. Upon working on the new technique, many times it was so much better than my original technique or idea.
Inventors and explorers live the quote.
Imagine Christopher Columbus or Walt Disney with fear and no vision! We would be living in a different world with no Walt Disney World or Disneyland. A world without Mickey Mouse!
Fear of failure will stop those mistakes from happening and also stopping whatever portals of discovery would have come out of the mistake.
A vivid imagination should never be wasted!
