You shouldn't give 100% at work.
Are you giving 100% at work? Or are you listening to your boss and giving 110%?
Go ahead and pump the brakes.
There's an idea called the "85% rule" which says instead of giving max effort, loosen up a little and give 85% instead. That keeps you more flexible and more present . . . helps you be more creative . . . and keeps you from burning out.
The rule actually comes from Carl Lewis . . . yes, the Olympic sprinter.
He'd generally start his races slower, because he was giving 85%. Then as he cranked things up, he'd pass the other runners who were too tense and slowing down. (Fast Company)
