If the best way to learn to succeed is to fail as fast as possible, then the second-best way is to watch someone else fail as fast as possible. Watching someone else screw up is a kind of rehearsal for your own eventual downfall. A close observation of someone else's attempt to resolve a difficulty is a great way to acquire real-world insight into whether and when to deploy their method in your own times of trouble.
