At the surface, it is tempting to say that the cultures of Silicon Valley and Boston promoted a different level of fear of failure. An interesting paper in the September, 2012 issue of Personality and Social Psychology Bulletin by Juliana Breines and Serena Chen suggests that the difference might actually lie in the self-compassion promoted by each region.
Self-compassion is the degree to which people treat themselves with warmth and understanding. People are not hard on themselves are treating themselves with self-compassion. At one level, this might feel similar to self-esteem, which is the degree to which people think of themselves positively. But, you can treat yourself with compassion without necessarily feeling positively toward yourself.
