if truly wanna gain success you should have balance of the two, you can be hard working all this century and have nothing.
thats what most unfortunate people are having right now, so much hard work but nothing in return because they working at place where salary is minimal, with luck if you happen to be in good country with high salary you're settled.
Nowadys hard work is good but like what you said mate it's nothing to do when we are so hardworking but the salary is minimal so that's the reason why other choose to (WORK SMARTER THAN WORK HARDER) which means they will find another source of income like selling or else investing in order to have an extra money. Cause if we stick to a minimum salary then we will not grow unless the salary will increase abig amount .
