I never regret anything I've done in my past because it led to who I am today and who I will become tomorrow.
At the end of your life, you will never regret not having passed one more test, not winning one more verdict or not closing one more deal. You will regret time not spent with a husband, a friend, a child, or a parent.
Never regret yesterday. Life is in you today and you make your tomorrow.
L. Ron Hubbard
