## When to use it

Present a method as especially important for a goal.

Often rhetorical; real tasks may have several valid approaches.

## The image & its use

A speaker may call regular practice the surest route to a skill. This expression presents a method with that degree of emphasis. Its background is a specialized philosophical image, while everyday use often means the essential or best approach. The phrase can be memorable in advice, but its certainty needs care. Most practical goals allow variation in tools, timing, and circumstances. Explain why the method matters and avoid implying that everyone must follow exactly the same routine to succeed.
