A great quote from how I met your mother

The great moments of your life wont neccesarily be the things you do, they'll also be the things that happen to you. Now I'm not saying you cant take action to affect the out come of your life, you have to take action, and you will. But never forget, that on any day you can step out the front door and your whole life can change forever.

You see, the universe has a plan kids. And that plan is always in motion. A butterfly flaps its wings, and it starts to rain. Its a scary thought but its also kind of wonderful. All the parts of the machine constantly working, making sure you end up exactly where your supposed to be, exactly when your supposed to be there.

The right place, at the right time.
