Recently I heard a very insightful comment made by an author [name unknown] who studied highly successful business people. The comment hit me like a ton of bricks - one of those aha moments that makes it seem as if we always knew this but just never thought about it. She said that the one common trait that she noticed in everyone studied was that they don't blame other people or events for their failures. Rather than saying, such and such failed because of so and so, they would say something more like "the failure resulted from my failure to do action X, or I failed to realize Y, etc. They always took responsiblity for their failures and then considered what they should have done differently. It was all about what they did wrong and how to improve themselves. It also struck me that this is a truth valid for any pursuit.
