“There are no mistakes, just lines that you're not happy with.”
“There are no mistakes, just happy accidents.”
“We don't make mistakes, just happy little accidents.”
“...when you're hard and unyielding your words score me with lines - I hate lines - I want curves - curves are happy like a snowman ...”
“I'm just a notch on your bedpost but you're just a line in a song.”
“We don't have mistakes here, we just have happy accidents.”
