I absolutely agree with the premise that solving somebody else's problem or getting an outside opinion is highly beneficial because it allows you to approach a problem with a beginner's mind.

However, in the real world this solution obviously doesn't work because you can't cut a rope lengthwise without the rope coming undone.
