O'Leary obviously has some good money making practices however you can concentrate on the money side of things too heavily. A weakness in the path he is taking is he is not making any friends. Blue code’s post touched on this. There is inevitably some point in the proceedings of any endeavour where you need friends. In the airline industry this point may be when you eventually have an accident. At this point if most people hate you your life is going to be more difficult. This is just a fact of life. While things are going good nurture your friendships because you may need them one day and it does not cost anything. Politeness, courtesy, being a little humble etc all play a part in this.
