I especially enjoyed that part when he was first learning to ride the new bike, and could do it, until he broke his concentration. I'm at that stage now, with un-brainwashing myself with Mormonism. I have to make that conscious effort to alter my thinking, but if I get distracted in a group situation, or if I'm sick or too tired, I slip back into those old superstitions, guilt, and self-loathing. For example, I still give certain unqualified men authority over me, as a reflex reaction, in response to their arrogant bluster and bossiness. I have to consciously stop and think about the fact that they have no "God ordained" authority, no credentials, and no rightful place in my life.
It is almost as opposite as that bicycle. Right is Left. Right is Wrong. Mormonism is full of lies, and it takes time to navigate with the truth, instead.
Eight months! This is also a good lesson in being patient with yourself.
