I found this in an article I was reading:
"Please do me this great service and please do me this great favor and please do yourself this great favor. And try to remember, 10 years from now, when you're second guessing this decision that you made, that you made the very best decision that you could make on this day with the information that you had today. As the years go by, you'll have more information and you might wish that you had done things differently. But just don't forget that on the day that you had to make the choice you didn't know and you only knew what you have now. Don't abuse yourself later for what you didn't know now."
