That is a vast question, one that only I can answer—and yet, most of us ask it.

Perhaps this is because there is no simple answer. We are multifaceted. We are sons and daughters. We are children, then adults. We are men or women. We are emotions. We are so many things, and these aspects of us evolve over time. Who we are today is likely to be different from who we will become in a few years.

So rather than trying to find a simple answer to such a complex question, why not embrace who we are now and let the rest unfold over time?

Another way to approach this is to think about who I aspire to be—and make that my North Star.
I do not need to know exactly who I am or why I am here to define the person I want to become. I do not need to be on a mission to save the world or end hunger to be a good person. I can start at my own level, by taking care of myself and the people I love—and creating a ripple effect from there.

Consider the night sky, with all its stars. How beautiful it is! There is no need to choose just one star: it is the combination of all of them that creates the beauty.
The same applies to who I am: I do not need to define myself by one aspect or reduce myself to a single idea. I can simply be—and enjoy being multifaceted.
