The most efficient way to make money anywhere in the world is to start a company that fills a gap in the market. This can be done by addressing a previously ignored need or by creating the market.

The idea of a best way implies other desirable aspects which has wide implications. Various perspectives might involve work environment, impact of the work itself or social aspects. My mother for example would say the best way to make money is to have someone hire you to work as a librarian as library work well suits her personality and goals in life.

The best way to put my mind and body to work at the moment is studying and gaining skills. The focus of the skill gathering is in psychology and computer science. Eventually that will feed me into a pretty marketable career either as a higher level computer worker or within the community of social sciences.

Neither of the above two perspectives involve the most effective ways to gather masses of money. This is because money is the smallest part of becoming an upper level professional. If a person is intelligent and reasonably talented they can easily find a job that will provide enough money for them to be satisfied. The difficulty arises from the other aspects of a career.

I personally have no inner drive to build a business. Too many businesses fail and leave their founder in debt for it to be a viable career path. They also involve administrative tasks and work hours that are a poor fit to my skills.

The best path for a human to make money is to effectively gather a sufficient benefits package in exchange for rewarding and enjoyable work.
