The corner you cut once becomes the corner you cut every time. Habits never ask how they started.

A shortcut taken under pressure gets stored as a method, not as an exception. Next time the situation is slightly easier and you take it anyway, because the path is already worn. Nothing in a habit remembers that it began as a one-off under unusual circumstances, which is how temporary compromises quietly become your standard.

When you skip a step, mark it as skipped rather than letting it pass unnoticed. Do the full version next time even if the short one worked. The second instance is what decides whether it becomes permanent.
