Amen Brother Neil!

Be proud of your mistakes. Well, proud may not be exactly the right word, but respect them, treasure them, be kind to them, learn from them. And, more than that, and more important than that, make them. Make mistakes. Make great mistakes, make wonderful mistakes, make glorious mistakes. Better to make a hundred mistakes than to stare at a blank piece of paper too scared to do anything wrong..
Neil Gaiman

The only think I would add to this is that it applies to more than just writing. Too much in this world is left untried for fear of making a mistake.
