The Dangers of “Just This Once”

“Just this once.”

It’s a phrase that has sparked many stories and sayings, including “the camel’s nose under the tent” and If You Give a Mouse a Cookie. Both depend on the idea of “just this once.”

The phrase “Just this once” might seem innocent, but it carries considerable weight, according to the late Harvard Business School Professor Clay Christensen. The esteemed professor, as explored in his book, How Will You Measure Your Life?, observed a curious pattern among his high-achieving peers. Despite their professional triumphs, many were grappling with personal turmoil – from failed marriages and children struggling with drugs to simmering scandals.

Christensen’s insights were deeply influenced by his upbringing in a devoutly religious family where strong moral codes were a way of life. From early on, he resolved that Sundays were exclusively for God and family, a rule he adhered to throughout his life. This commitment was put to the test during his time at Oxford University on a prestigious Rhodes Scholarship. Christensen, a shining star on the basketball court, faced a moral quandary when his team advanced to the UK’s version of the NCAA Final Four.

The pivotal semi-final match was scheduled on a Sunday, putting Christensen’s conviction under intense scrutiny. Despite immense pressure from his coach and teammates to play, Christensen stood his ground. He chose his commitment over the game, leading to Oxford’s defeat. While his decision may have cost his team the championship, it won him something far greater – the assurance of remaining true to his beliefs.

All sin starts with “just this once.” A first lie. A first cheat. A first broken promise. The serpent in the Garden of Eden did nothing more than say, “just take one bite.” One was enough.

Once you make an exception, it becomes easier to make the next, and the next, and the next. Soon, your character crumbles like dried-out clay. “Just this once” opens the lid to Pandora’s Box. Strained marriages, neglected kids, and shifty business deals litter lives. Once you cross the bright line, danger lies ahead.

Every small decision is a massive one. Stop and listen to your mind say, “just this once.” When you hear it, run the other way. It won’t be just once. It will be the first of many.
