But that's a great example of a lesson to be learned from stories about quitting: sometimes you do it because a hard reset is the best option. Knowing where that point lies is valuable knowledge.
Personally, I want to hear stories about failure more than stories about success. Stories about success are boring and repetitive, because they usually revolve around some combination of luck and persistence. But the truly hard decisions in life come when you're spinning your wheels, and you need to determine when it's time to cut your losses.
