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.
The Olympic sprinter was known for starting races at a seemingly relaxed pace, only to surge past competitors in the final stretch.
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:
Stay mentally flexible
Be more present and aware
Boost your creativity
Avoid burnout
