The practice of reviewing your own match play — both wins and losses — to identify patterns, recurring errors, and areas for targeted improvement. "You either win or you learn." Film yourself to compare what you feel vs. what's actually happening.
After matches, review specific points (not just the outcome). Ask: how often am I losing points in the same fashion? Track where you are when points are lost — on serve or return? If mostly on serve, the mistakes were "free" (no points lost) and may reflect appropriate aggression. Film yourself with a phone or GoPro. Compare "what you feel" vs "what's real" — they're rarely the same. Look for: recurring positional errors, balance issues, shot selection patterns, timing problems. Use the findings to set drilling priorities.
What you feel is happening on court and what's actually happening are rarely the same. Without film, you're diagnosing your game from corrupted data. Players consistently overestimate their body height, underestimate their swing length, and misremember positioning. The camera is the only honest coach.
Cincola: "Aim small, miss small." Every single shot requires three deliberate intentions BEFORE you hit: (1) spin type (topspin, slice, flat), (2) trajectory (high arc, flat, low), (3) pace (soft, medium, hard). Without these three intentions, there's no feedback loop — you can't diagnose what went wrong because you never defined what "right" looked like. With intention: "too high," "not enough topspin," "hit too hard" — now you can fix it. Without: "that didn't work" — no actionable information.
