The line comes from Star Wars: Episode V – The Empire Strikes Back, released in 1980, during Luke Skywalker's training on Dagobah. Jedi Master Yoda, voiced and performed by Frank Oz, corrects Luke after he doubts he can lift his X-wing from the swamp. The quote became one of the saga's most repeated lines, alongside moments like Darth Vader NOOOOOOOOO!, and is still quoted in sports, classrooms and self-improvement posts. Its simple wording and memorable delivery have kept it in circulation for decades as shorthand for full commitment.
