Step Six: Obligated to Go Forward

Step Six has always seemed to me to be the most theoretical of the Twelve Steps. What, exactly, do we mean by "entirely ready"? What if I am only a little bit ready? Halfway ready? Seventy-five percent ready? Can I still approach Step Six? I think the answer is yes, and I'd go further: despite the degree of readiness I might or might not possess on a given day, I am obligated to go forward.
