This grammar shows one thing has a big effect. Other phrases like "~次第で" (shidai-de) mean "it depends on." They are more formal. They do not show surprise. For example, you would not say "just effort alone." You would say "depending on your effort." This grammar works best with single, clear things. Like "one word" or "one mistake."
