It's understandable to feel small or insignificant in the grand scheme of things, but it's important to remember that every person's life has value and meaning, regardless of how many other people there are in the world. Having a sense of purpose can give your life direction, focus, and meaning, and can help you to feel more fulfilled and satisfied with your life. It can also give you a sense of connection to others, as your actions and choices can have an impact on the people around you and the world in general. Ultimately, the purpose of your life is something that only you can decide, and it can change and evolve over time as you grow and learn. It's important to take the time to think about what is most meaningful and fulfilling to you, and to pursue those things in your life.
