The inspiration behind “Just Do It” has a surprisingly dark origin. When you dive into the dark roots of Nike’s “Just Do It” ad slogan, you find it was born from death row inmate Gary Gilmore’s chilling last words—”Let’s do it”—before his 1977 execution for double murder. Advertising wizard Dan Wieden found the words intriguing, focused, and channeling a vibe that showcased a raw determination to get things done. Wieden was struck by the resolve in those words, adapting them to “Just Do It” to evoke determination in the face of uncertainty. He later reflected that the phrase captured an “ultimate act of intention,” –a motivational mantra. Skeptical at first, Nike’s Phil Knight let it stick—and history was made. Rock this tee as your ultimate call to crush doubts and charge ahead.
