I like thinking of it as a choice. I didn't arrive at atheism because I got a lightning bolt of... anti faith? After years of hearing stories in church, I was slowly convinced that the story I was hearing in science classes made more sense. I do choose to be an atheist.
Oh... I am approaching working on step 2 and then 3, the scariest steps for me! I decided if I had an imaginary friend when I was 5, I'm not too good to have one now. What the he11. I make a total fool of myself with alcohol and other people know it, why should it bother me to talk to an imaginary friend inside my head where no one else can hear me??
(Following a suggestion I read in "12 steps on Buddha's Path" by Laura S. I adore this book.)
