To many people, the purpose of life is very clear. It has been laid out clearly either by their parents, teachers or religious leaders. For others, it is much harder to work out. In fact, many philosophers have argued for centuries about what the true purpose of life is. There is a distinction between what the purpose of any life is and what it means to an individual, of course. Some people believe they have found a purpose in their life if, for example, they do a job that they find fulfilling. To others, the purpose of all human life is to work towards a higher purpose that is bigger than any individual. Broadly speaking, the latter is a spiritual interpretation of a life's purpose.
