Unlearning is half of learning. Some of what you know is just old wiring.

Plenty of what you believe was installed early, by whoever was around, and has never been examined since. It sits in the same drawer as things you actually checked, which is why it feels equally true. Making room for new understanding often means removing something first rather than stacking on top. That removal is slower than learning, because nothing about it feels like progress.

Pick one thing you are certain about and trace where the certainty came from. If the answer is a person rather than evidence, hold it more loosely this week. Let one old rule be tested instead of obeyed.
