Yeah, I think the biggest danger is paying too much attention to what other people are doing. It's not that you can't learn from success or failure, but these days that information is far too accessible. The talent and conditions that lead to success in one case are probably completely inactionable for anyone else by the time the story is told.
What you really need is to hone your ability to recognize success and failure on a minute-by-minute basis in your own startup.
