You do not become stronger by refusing every signal that you are tired.

Overriding tiredness once is a skill worth having. Overriding it as a policy is not strength, it is the removal of a warning system, and it leaves you unable to tell an ordinary hard day from the beginning of something serious. Strength includes accurate reading of your own condition, because power you cannot regulate tends to break the thing carrying it.

This week, respond to one signal of tiredness rather than pushing past it. Notice what happens to the next day. Learning when to yield is part of building capacity, not a retreat from it.
