I will not waste time on regret.

Regret arrives with useful information attached, and then keeps talking long after the useful part is over.

The first pass does something real. You learn what you would do differently, you see which line you crossed. The ninth pass at two in the morning, running the same conversation with better answers you did not give, teaches nothing new. It only charges rent.

Not spending time on it does not mean deciding the thing did not matter. It means letting the review end when the review is finished, and catching the moment you stopped learning and started rehearsing.
