Not at all. The majority of people thinks that if you work harder and harder and harder, you'll eventually get rich. In the outside world, this is a misconception. Rich people doesn't have to go outside and work as hard as they could just to become rich. They worked "smarter" instead of doing harder the exact same thing that they do before.

There's this saying that goes like this: "An average worker works harder to become successful. But an exceptional worker sharpens his saw most of the time." The latter basically is the one who actually reaches better success with lesser effort.
