You will not reach your full potential, and you will have cheated society of the full benefit of your talent and ability. Whatever your occupation, you have a duty to the society of which you are a member. If you are a soldier, your duty is to protect that society. If you are in business or industry, your duty is to create and manage the jobs, wealth, and products of that society. Therefore, failure will be harmful not only to you, but also to society, just as success will be beneficial not only to you, but also to society.
Every individual has the potential to do great things.
To reach this potential it is necessary to discover your special abilities and qualifications. This means that you should always attempt new tasks and accept responsibility for untried assignments whenever they are offered. A leader accepts responsibility. This means that the welfare of those that you lead must always come before your own well being. Therefore, while your primary duty is the accomplish of your organization's mission, the welfare of your subordinates comes second, and your own welfare last.
