Life?

Life. It's a crazy thing to live, especially when you think your life should be lived a different way and it isn't. How do you accept the life that is and not what you dream it to be? Is there a way to make the dreams in your head match reality? I always had an idea of what I thought I wanted, yet something completely different would come into my life and it would resinate better with me. So, how I believe my life should be isn't true at all. How do you know what you truly want, or what is truly meant to be your life?
