Humility

The dictionary defines humility as modesty, lacking pretence, not believing that you are superior to others. Another definition is simply "the quality or condition of being humble." We often confuse humility with being timid. Humility is not about degrading ourselves its all about maintaining our pride in who we are and our achievements. But the key is to do that without arrogance. That excessive arrogant pride is what can derail us from reaching our goals. It's about that quiet confidence that is missing from today's self promoting society. It's about being content to let others discover the layers of our talents without having to boast about them. It's a lack of arrogance, not a lack of aggressiveness in the pursuit of achievement.
It has been shown that some of the most successful CEO's all have one very important quality in common and that is humility. These leaders are a mix of intense professional will and extreme personal humility. They will create superb results but shun public adulation, and are never boastful. That is so important to not only being able to perform well but also to be humble enough to share credit with others.
An interesting dichotomy is that, often, the higher people rise, the more they have accomplished, the higher the humility index. Those who achieve the most brag the least, and the more secure they are in themselves, the more humble they are. It's comforting to know that its the more humble people that are the most successful. It may not be money and fame that you are blessed with but humility will bring you success in life.
