Pretty cool; it's encouraging to hear your narrative.
Although I think you had it easier, since you were a car free bus rider for so long before switching. You had already cured yourself of any automobile addiction. Once you learn how to survive without a car, shifting to another car-free mode has to be the easier shift.
