In life we do things. Some we wish we never had done and others we wish we could replay over in our heads a million times. But they all make us who we are. In the end, they shape ever detail about us. If we were to reverse any of them, we wouldn't be the person we are. So just live. Make mistakes. Make amazing memories. But never, ever second guess who you are, where you have been and most importantly, where it is you are going.
