Without using the term, everyone has marked out a path in life--a path can be defined as a road map that guides you to a goal. Because every day presents some kind of goal, however small, being on a path is inevitable. It doesn't have to be a conscious choice. Yet at a certain point it dawns on most people that they have larger goals, even lifetime goals, that require long-term planning. At this point choosing a path does become a conscious decision.
On the surface, it would appear that life presents many paths, because so many goals present themselves: finding the right partner, raising a family, settling on a career, pursuing success, earning more money, saving a nest egg for retirement. These are socially shared goals, to which more can be added, such as finding God or writing a novel. But if you look deeper, everything on this list boils down to one path only.
This is the path of desire, which is the most natural path, since we all have desires. The impetus that keeps people on the path of desire is universal but also logical. If you want to eat breakfast, make friends, do something you enjoy, or have any other everyday desire, it's logical that expanding your desires and following a bigger dream should serve as a reliable path in life. In fact, because 99% of the human race follows the path of desire, this should prove how defective it is. The problems of poverty, crime, war, hunger, disease, and mental anguish haven't been solved around the world, and one or more of these problems reaches into everyone's life.
