My most important prayer-right now

I'm not a jesus freak, but I posted this on my bathroom mirror.

God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. Living one day at a time, enjoying one moment at a time; accepting hardship as a pathway to peace, taking as Jesus did this sinful world as it is, not as I would have it, trusting that you will make all things right if I surrender to your will; so that I may be reasonably happy in this life and supremely happy with you in the next.
