It’s dogged as does it. It ain’t thinking about it.

In this colloquial, proverb-like phrasing, the speaker dismisses over-deliberation in favor of persistence. “Dogged” suggests tenacity and steady effort; the point is that success (or simply getting something done) comes from continuing to act rather than repeatedly “thinking about it.” The second sentence sharpens the idea: reflection alone is not the engine of achievement—habit, grit, and follow-through are. The dialect (“ain’t”) also signals a practical, working-world voice, implying a contrast between plain common sense and more self-conscious, intellectualized approaches to effort.
