In common sense, I think hard work is more like working in an office that requires the employees to go to work at 7:30 a.m. (or 8am) and return home by 5 or 6 p.m., depending on where they are working, but smart work is more like those that work at home right on their phones or computers, and yet on a daily, weekly, or monthly basis, they always have money that flows into their accounts, and most of the smart workers don't need less time, less energy, or less stress to perform their online jobs in order to get paid. I know of a freelancer and an affiliate marketer who make about $1k to $2k every month and some months more. The fact is that some people who are going from their homes to work every day and closing late are not earning even up to what some of these affiliate marketers are earning. Another example are most of these social media celebrities who make some funny and educational skits and get paid daily.
