I learned from a guy who used to post here at SR. He taught me that once I did step three, turned my life and my will over to my higher power, that what happens now as I go forward is not up to me, it's none of my business... it's His
My own experience? For me it's been one of trust and detachment... and it's progress not perfection.
There is no way to adequately explain my higher power, God... I just know He's there and I (try) to let go absolutely.
