This equation when understood can go a long way to help you make some smart decisions and choices in life. Over the years I have learnt to appreciate this equation so much because it guides me a lot. Hard work cannot do all the magic in a wrong system . A lot of people work so hard but are not able to make due their effort In terms of income, simply because their effort is locked is a bad system. System can be a skill, service and product and perhaps an industry that can reward you of your effort. It time so look at all the systems you have been killing yourself for all these years and make a smart move while you are in those systems. Time + System = Income . I know you will review this into details and it will make a lot of sense to you.
