In a study done at Stanford University among top achievers, they concluded that skills is not the main factor of their success. It is about 14% - 22% of success factor is based on skills. The main contributing factor is attitude, because if someone with good attitude, skills is no longer an issue because they will overcome it by themselves if it is necessary in getting the job done.
Leading the Pyramid
What makes successful people have the drive in their life? What makes them persevere? What makes them doing things beyond what money can pay?

1. Skills
At the bottom of the pyramid is actually skills. At this level, people have skills but they trade their skills with money. Most of the time, either they provide single service such as plumber, barber or operator, or people who are working in a company as an operator, clerk or salesman, they trade their skills with money. Either they are paid by the job done, or they are paid per hour. What happened was if they were to do more than what has been agreed, they will claim more money. Such as over-time or some extra out-of-scope job. The key thing is, they trade skills for money and normally they are operating at an individual level.
