You are who you love, and everything in between. You even are what you love, and whatever you love more is what you project to the world. Sometimes (often), you don't know what or who you love. So you're an open book, a soul blowing in the wind, ready and willing to try anything and everything to fill it.
Because of course, if you have a soul, you have a hole. And if you don't know what to fill that inner space with, it's a lurking emptiness that reoccurs when you least except. Some things (and people) will fill it temporary, but it doesn't stick. If you're lucky, you'll find something lasting before you pass, and with it, the grandest sense of serenity.
