The 5 most important words

I need a drink now?
The weekend is finally here?

Actually... no.  What would you say are the five most important words?  At first I thought this was an open-ended question but it was quickly answered by the speaker at the Cardinal Stritch graduation ceremony this past weekend in Milwaukee.  Please, thank you, I'm sorry.  Ha.  These kids are graduating college with the same rules or guidelines they learned in kindergarten!  All I Really Need to to Know, I Learned in Kindergarten?  Bases, covered.

What would you say are the next 5 most important words?  Why?
