If you’re constantly being told to give 100% — or worse, 110% — at work, it might be time to hit the brakes. According to a concept called the “85% rule,” putting in just enough effort could actually make you better at your job.
The idea? Stop overexerting yourself. Instead of running on all cylinders every minute of the day, aim to give about 85% effort. It sounds counterintuitive, especially in hustle culture, but there’s science — and Olympic gold — behind it.
The rule was popularized by none other than track legend Carl Lewis.
Why? Because he wasn’t tensed up and burning out in the first half — he was running at about 85%, saving the rest for when it really counted.
In a work setting, the same logic applies. Operating just below your maximum capacity can actually help you:
Think of it like trying to drive a car with your foot glued to the gas pedal — you’re going to burn through your fuel fast and probably miss your turns.
Of course, this doesn’t mean slacking off. The 85% rule isn’t about doing the bare minimum — it’s about working smart, not just hard. It’s a reminder that peak performance often comes when we dial it back just enough to stay sharp, steady, and sustainable.
So the next time someone tells you to give 110%, just smile and give them your well-balanced 85. Carl Lewis would approve.
