Over the course of a lifetime, one only experiences a sense of progress through beginnings and endpoints. Without them, one feels a sense of stagnation that, being unnatural, causes a growing discomfort; which, even when masked, tends to intensify until it erupts when least expected—and then there is no way to recover the time that has been lost. That is why it is essential to set them regularly as milestones marking progress. This is how one truly evolves: by maintaining the initiative for new beginnings and the maturity to realize that something has already fulfilled its purpose.
