I think everyone is different and finds what's comfortable for them. I usually say a prayer at night for God (my HP) to bless the special people and pets in my life. But I often just "talk" to him throughout my day....very informal..like "okay, I'm a little stressed about this situation...can you help me out here?" or a simple "thank you" when I am reminded of the many things I have to be grateful for.
My friend is the same way in her prayers. She will say "okay, you know who you're dealing with here....how about a really obvious sign that I'm doing the right thing". Funny thing is, we always get an answer if we look for it.
And like Jersey....the serenity prayer is my favorite.
Hugs and prayers!
