The practice of deliberately designing your mental habits, thought patterns, and internal narratives to optimize for happiness, productivity, or at least functional survival. It's the attempt to rewire your brain's default settings, replacing the factory-installed "catastrophize everything" app with a custom-built "moderate optimism" operating system. The problem is that your brain's legacy code is deeply resistant to updates, and every time you try to install a new "don't panic" patch, the system reverts to its factory settings of "panic appropriately (and also inappropriately)."
Example: "He tried some metacognitive engineering, installing a new mental habit where he'd reframe every negative thought. When he thought 'I'm going to fail this presentation,' he'd force himself to think 'I'm going to do my best.' It worked great until his brain crashed and started reframing 'I need milk' into 'I am one with the milky universe.'"
