Planning is doing the planning thing, but it is not doing the battle thing.
And running the marathon is just running the marathon? I disagree. Big part of running the marathon is in the preparation. Weeks after weeks of training and not skipping a single session. The marathon itself is the tip of the iceberg; important but not the whole "thing".
But both are doing the winning thing, which is more valuable than just the battle thing. Unless you do it just for fun and don't mind the result.
