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?
The flow of money coming in from various sources but you do not have the management to ensure that the money is invested well then you are just like a door for money to enter and exit so that you do not have any profit. I agree that the word enough for a source of income is much better than excessive. At least all your financial arrangements are guaranteed to provide controllable profits.
