A life lesson that we should all take to heart

I saw this one and just KNEW it needed to be shared.

I think once you realize this, you can understand all the other lessons that you will learn over the course of your lifetime.

You are not "living on the outside".
You are not or should not be just "looking in".
You should be LIVING your life so that you can continue to learn what you need to do each and every day!
