I have learned advice from books about being successful. And there it is stated that the people we call rich have at least 3 sources of income. And to achieve financial freedom we need at least 7 incomes. Such as salaries, dividends, rental properties, capital gains and many other types.
We need to be a reader because readers are always leaders, in reading, we get exposed to some certain things that needs more of our salient attention, we need to expand our coast of learning and erase the limit to how far we can go in reading, in so doing we are getting more experience in a logical format through reading books and the ideas gotten from doing so, but I don't think we really have to engage into having upto seven businesses or what we do before we can be successful, this is not saying about diversification, but avoiding waste of time in doing other things unproductive.
