In retrospect, we would all make better decisions.
We would be smarter.
We'd eat better.
We would treat people differently.
But living in this world is a waste.
We cannot question every decision we make, judge ourselves and live with regret.
Take a moment to learn.
Look forward for a moment to get an idea of where you are going.
And then live in the present.
Do your best with what you have and what you know today.
