“Success requires no explanations. Failure permits no alibis.” ~ Napoleon Hill from Think and Grow Rich

Hill has a bunch of sweet lists (from the causes of failure to the causes of fear and others). How about a few of the major causes of failure? 

• Lack of a well-defined purpose in life.

• Lack of ambition to aim above mediocrity.

• Lack of self-discipline.

• Lack of concentration of effort.

• Lack of enthusiasm.

• Inability to cooperate with others.

How do you stack up and how can you grow in these areas?
