It

It is what it is.
It was what it was.
It's going to be what it's going to be.

Don't sweat it. Embrace it. Live it.

If it's out of your control, let it go. You cannot change it. Don't bother trying or even thinking about what if you could. You can't. It is what it is.

As far as the past goes, is was what it was. All the thinking, analyzing in the world won't change it. It's done. It's over. Let it go. Learn your lessons and move forward.

Trust that what's going to be will be. It kind of goes without saying. Do what you can about what you can and let the rest of it happen as it's going to no matter what you think or do. Think the serenity prayer: God grant me the serenity to accept the things I cannot change, the courage to change the things I can and the wisdom to know the difference.

It is what it is.
It was what it was.
It's going to be what it's going to be.

Profoundly simple?
Simply profound?
