You know the old trick at a job interview, where they ask you your weaknesses, and you say, "I come in too early, I stay too late, I work too hard, and I care too much"?
Well . . . TWIST. It turns out those actually ARE weaknesses.
A new study out of London found it's BAD for your career if you work too hard.
The researchers found that when people were too intense at their job and they put in extra long hours, they wound up more stressed and more fatigued . . . and their work really suffered.
In other words, whatever you gain in your boss's eyes by working so hard is RUINED by the fact that your results aren't that good. (And don't try sucking up to them, because THAT makes you worse at your job too.)
So the BEST thing you can do for your career is work hard but not TOO hard.
