Stumbling isn’t the same as walking away. Get up and keep the same direction.

A stumble and a change of direction are different events, and shame is terrible at telling them apart. You do the old thing again and immediately conclude the whole attempt is over, which is how one bad night turns into a bad month. Falling over while facing forward is still facing forward. What matters is the heading you get back up on, not the fact that you went down.

If you slipped recently, resume the same day rather than starting again on Monday. Same direction, nothing renegotiated. The gap is what does the damage, not the fall.
