You become mentally dangerous when excuses stop sounding intelligent to you.

For most people, excuses sound like analysis from the inside. They come with reasons, context, and mitigating factors, and they are persuasive precisely because they contain some truth. Something changes when you start hearing your own version of them and recognising the shape rather than the content. Once the pattern is audible, it loses most of its power over your next hour.

Start listening for your three most common reasons, the ones that appear regardless of the situation. When one shows up, name it silently and continue anyway. The point is not to be harsh with yourself; it is to stop being persuaded by material you wrote.
