I didn't read any of that in this article. Maybe the not accepting excuses point? One type of leader I've encountered in my career is the one who won't accept accept excuses. "If you can't do it, I'll get someone who can." It's not personal, it's a business. Another type of leader I've encountered is one who builds the team up and accepts the occasional failure, knowing that in the long run there may be more wins because the team will grow professionally. Personally, as a leader I find myself more in the second group. However, both are really equally valid, in the long run--in that they have an equal chance to achieve business goals. How are the other two points (Don't languish in what you can't change, look for a solution in every failure) an "American" viewpoint?
