H is for H.O.W. It means how the program works, "Honesty, Open Mindedness, and Willingness. I also thing that the spiritual principles for Step One is Honest, Surrender, and Acceptance.
Unless I can get honest with me, open my mind to other ideas and concepts other than my own (my best thinking got me to the doors of recovery), and willing to go to any length, not to have that first drink in today and willing to do what ever it takes to maintain my sobriety.
One alcoholic/addict talking and sharing with each other is how the program works for me.
