Let’s take a vegan at a restaurant. When the menu arrives, they’ve already discounted 80% of the potential options. As they go through the menu, they don’t even consider the plates with meat. It’s as if they don’t exist. They simply zone in on the choices in line with their underlying code. This makes their life easy—no back and forth between dishes. There’s no overanalyzing and spending their precious energy on best- or worst-case scenarios. Vegan eating, then, is simply an example of having a strict code in life to guide us.
