Beat the version of you that would have stopped here.

There is a point in most efforts where an earlier version of you would have found the exit reasonable, and that point is usually well before the end. Passing it is a specific, satisfying kind of progress, because you are not competing against anyone else’s endurance, only your own habit of stopping.

When you next feel the urge to stop, notice whether it is genuine limit or familiar pattern. If it is the pattern, go one increment further. That increment is where the change actually happens.
