Well, I may not do it well, but I try to live every day like it is my last.
As for the messy details, I'm a bit more of a slob on that one. But I won't be here to worry about it, will I?
If tomorrow was D day then I would just try to chill out, maybe smoke a a few doobs and enjoy the day.
Read a few other answers. What's with all the praying? Worried you weren't up to scratch? A bit late isn't it?
Or, as Lisa Simpson said: "Prayer, the last refuge of a scoundrel" which, I believe, is a borrowed quote: "Patriotism is the last refuge of a scoundrel" from Samuel Johnson, 1775
