After a big win, go back to practice like you lost. Winning makes people skip the stuff that made them win.

Success quietly removes the pressure that produced it. The drills feel less urgent, the preparation feels optional, and the decline begins from a position that looks safe from inside. Nothing warns you, because results from the old work are still arriving while the new work has already thinned out.

Treat the week after something goes well as the week most at risk. Keep the same routine you had before anyone was congratulating you. Let the win be information about the method rather than permission to drop it.
