A limit discovered years ago may belong to someone you no longer are.

The person who ran into that wall had different habits, less experience, and a different life around them. Their finding was accurate about them. Applying it now means letting someone who no longer exists make decisions on your behalf, and they are working from information that has been out of date for years.

Think of a limit you accepted a long time ago and ask what has changed about you since. If the honest answer is quite a lot, the limit deserves rechecking. You do not have to overturn it, only stop treating it as settled.
