You must not dither – swim like you’re running through a minefield.

Our reading
An editorial interpretation.
The speaker demands decisive movement by comparing swimming to running through a minefield. The dangerous image makes hesitation sound especially costly. Read as forceful encouragement, the line uses an extreme comparison to urge commitment; it is not a literal explanation of how to cross such terrain.
