Making money work for you instead of always working for money comes down to building a streams of income that don’t rely on your time alone. I think, it’s not about quitting your good paying job overnight, but is all about you using the money you earn to create assets that pay you back overtime.
Definitely creating wealth requires more than just working and getting paid but to used the money gotten from the paid job to reinvest in other things. The richest men in the world didn't rely only on salary. Salary doesn't create wealth rather salary is used to explore or diversify into other forms of investment which will yield interest in the long run. Making money work for you instead of always working for money is the slogan of successful entrepreneurs who have succeeded from one form of business to another. And trust me it's definitely a self motivational quotes that people should take seriously allways for self motivation, and putting it in practice.
