Successful people work smart - not necessarily hard or for themselves.
Why work hard for 8 hours a day if you can swing it in a way where you can work for only 4 to do the same thing. Then if you decide to work the other 4 your can effectively double your daily output.
Also if you don't own the business you don't necessarily have a vested interest in it's success or failure - which can be separate from your own success or failure.
What the definition of smart work? To work smart requires knowledge, intuition, experience, interaction, perseverance and focus. To achieve that requires hard work. You basically trade time for knowledge but it still hard work.
