I'd like to see some analysis of failure, some stories about people who worked hard and gave it their all but just didn't get anywhere, or who got derailed by one thing or another and lost their motivation. Of course, who would want to be that example?
In the world of mountaineering there's a famous archive of accident data, Accidents in North American Mountaineering, that's a must-read for anyone contemplating getting into climbing mountains with any seriousness. The stories are many - bad judgment, bad luck, lack of preparation, exceeding one's capabilities, etc. but they're all very informative.
There are many ways to go wrong, and maybe that information is more valuable than examples where everything goes right.
