Hardworking is a necessity for surviving but sometime it doesn't matter how hardworking one can be but the ability for an individual to work smart, discover his/her talent where necessary and know how to apply it in order to make the best utilization of any little available opportunity. There many people that work for 20hours daily without a tangible wages but smart person that now how to discover opportunities can work for less than 20hours daily and make a better income.
Work smart and not work hard, that's what everyone need today and not dispense energy trying to make all the wealth. Though, there are some work that you don't have choice but to do them according to how they are meant, like a nursing would have to be at their work place all time before they can earn, a grocery store person would need to attend and get paid per hourly but their are some work that you don't need to dispense all the energy to get them done.
There also alternatives to other works than rely on particularly work that will dispense all your energy. I would rather work in grocery shop as attendance and get paid good amount of money than work in a site, I don't want my life to have short expectancy before I die, even though the pay is huge, you can actually do two part time work and get good more pays without stressing much.
