If you want success in life, you must achieve interdependence. We as a culture have been sold on the idea of independence. The early mountain men, then the pioneers, then technical heroes such as "Lucky" Lindbergh and John Glenn were portrayed as individuals who were brave and resourceful and successful. In truth, each of our heroes depends on others. The mountain man was ultimately dependent upon the craftsmen who made his rifle and other gear. In turn, the mountain man helped the craftsman design better gear as a result of his experience in the field. Our culture, when studied realistically, show how interdependence is always more successful than independence.
Consider a person who decides to work at a trade or profession. That person can only work a limited number of hours in a given period. Even if totally dedicated, that person must have time for rest, nutrition and maintenance of bodily functions. That person only has a maximum of 24 hours with which to work. Thus, his effect on everything, his bank account, his society, his company, is limited. However, if that individual can work with others to accomplish his goals, his limitation is bounded only by the number of people he can inspire. .
If, for example, a person was concerned about hungry children. That person could devote a portion of income to buying food and a portion of his or her day to feeding children who needed the nutrition. That person's effect would be very limited to a locality and just a few children. If that person, however, was to engage in building an organization of many people and raising funds with which to by truck loads of food, the effect of that person would be considerable. Mother Teresa is an example of someone who found herself at the head of an organization even though she probably only started out to help the poor. .
The same effect is true if your goal is to make money. Even the highest paid professional only makes a few hundred dollars an hour.
