They’re bigger. You’re faster, smarter, or more annoying. Find your edge.

Matching somebody strength for strength is the losing version of most competitions. When the other side holds the obvious advantage, the move is to change what the contest is about rather than out-muscle them at their own thing. Speed, preparation, patience, stubbornness, knowing the rules better than they do, all of these beat size regularly. The mistake is assuming there is one axis and you are behind on it.

Name the advantage they actually have, out loud, so you stop competing there. Then name one thing you do better and build around that. Play your game rather than theirs.
