“Efforts and courage are not enough without purpose and direction.”
-John F. Kennedy
Obsession must have a purpose first of all. The purpose of a tree, for example, is simply to grow toward the sun. This purpose is essentially the rudder, the element providing direction for the individual’s passion. A boat without a rudder and destination will never achieve its purpose, no matter how much wind is at its back, or how much fuel is provided.
A person’s purpose is typically more complex, but for a single passion, it is best to keep it simple. A good example is Einstein’s developed purpose, which can easily be gleaned from this quote: “The search for truth and knowledge is one of the finest attributes of man—though often it is most loudly voiced by those who strive for it the least”. He also said “If you want to have a happy life, tie it to a goal, not to people or things”. His purpose and goal was the search of truth and knowledge, specifically within the realm of science and physics.
