"its better to work SMARTER than harder" - true.
😉 However... I always do my best to work smarter when I word hard. You can always work smarter in order to achieve what others could but in a shorter time. This to me is just just limiting yourself and being lazy, why not work harder and achieve even more then expected, just because you can do it in half the time doesn't mean you can't do twice as much. Work smarter and harder, achieve greatness!
