Everything Happens for a Reason?

What does the quote "That there are no random acts. That we are all connected. That you can no more separate one life from another than you can separate a breeze from the wind." mean to me?  This quote means nothing to me. I don't believe that there is a grand plan. I believe that accidents just happen.  I don't believe in fate. I don't believe that we are all connected. I think we all have our separate lives.  I do believe the choices we make have an effect on us. If you want to change your life do something about it, don't wait for fate to intervene.  I understand why people want to think that everything happens for a reason and that we are all connected, I just don't see it that way. I understand what this quote is suggesting, I just don't share the author's opinion. After all this quote is in a fictional book.
