I have only one real prayer i say before bed, it was actualy part of the bible and was edited by Tupac, my priest liked it alot when dealing with us "city" kids.
"I shall fear no man but God, though i walk through the valley of death. And if i should die before i wake, dear god take me up to heaven"
When one little thing after another seems to be going wrong, I lift my eyes to the heavens and quietly say something like: "Murphy, are you about finished having fun with me yet?," the clouds roll away, and everything starts behaving as expected.
Either I'm defying all the laws of probability, or somebody's listening. I think the latter. Honestly try it a few times and share your failing or successful experiences.
