Carl tells Jake he is so clumsy and that he's always been a disappointment.
Jake learns what mistakes are important and what ones aren't and is able to take calculated risks to improve his life.
Jake becomes so afraid of making a mistake around Carl that he never tries anything new and leads a boring life.
