In a paper called "Habits in Everyday Life: How to Form Good Habits and Change Bad Ones", Wendy Wood calls attention to the neurology of habits, and how they have a recognisable neural signature. When you are learning a response you engage your associative basal ganglia, which involves the prefrontal cortex and supports working memory so you can make decisions. As you repeat the behavior in the same context, the information is reorganised in your brain. It shifts to the sensory motor loop that supports representations of cue response associations, and no longer retains information on the goal or outcome. This shift from goal directed to context cue response helps to explain why our habits are rigid behaviours.
Basically, with time, we forget why we do what we do. We wake up one morning - good morning :) - and wonder why we're going to work again. But this very realisation can help us "Sell to Ourselves" which was mentioned in the last Impossible. This shattering "why" is the breach one needs in a mental status-quo to start a grounds up change. When "Why" show up, it's very tempting to censor it. It's quite unwise however.
About censorship, Charles Bukowski writes: "My days, my years, my life has seen up and downs, lights and darknesses. If I wrote only and continually of the "light" and never mentioned the other, then as an artist I would be a liar. Censorship is the tool of those who have the need to hide actualities from themselves and from others. Their fear is only their inability to face what is real, and I can't vent any anger against them. I only feel this appalling sadness. Somewhere, in their upbringing, they were shielded against the total facts of our existence. They were only taught to look one way when many ways exist."
"Why" will creep up one day. Look past its weird old look. Ignore its drooling mouth and stupid eyes. "Why" has the soul of a child. "Why" will take you where many ways exist. Why censor your heart.
