Truly amazing words and inspiration to us all, thanks for sharing.

As a developer and designer, it makes me think the about "Code Block" when writing code.

Try running the code and viola; you have an error. After hour upon hour looking at the code you just can't find the error.

Step away from it, go to the gym, go shopping, have a nap. When you return the error is starring it the face; you forgot a SEMI-COLON! (Use the south approach).
