Existence .

Who I am is defined by the decisions I make, the people I surround myself with. The things I do everyday and what people remember me by.
Why I exist is because I am lucky enough to. And since I exist, I should make the most of it. Make a difference if I can in one way or another. We can all decide why we exist. Some people exist without a purpose while some continuously find purpose and ways to make their existence fulfilling and impactful. And that, is what makes them who they are.

So stop searching for the answer. You can't "find" the answer. YOU are the answer. The only thing is, you can chose whether you want it to be a good answer or a bad answer.
