Having multiple sources of income is good but when there isn't stability of the outcome of income or wages at the end of the day, there is sure to be poverty and lack of financial power.
Therefore, do you think that a source of income must be steady enough for years, before one can be financially free or rich or very wealthy, depending on the source(s) of income?
No. all sources of income must not be stable before one can be classified rich, reason been that, firstly no one can be able to get involved in all sources of income, you can only invest as much as you and all those who are willing and reliable to work with, to foster good inflow and outflow, however when one began to make stable profit in business with all inclusiveness, like formal and informal business education thereafter you now need a reliable financial insurance support,
