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?
To be classified as being rich I think it involves alot but not just having a steady income, you can have enough inflow of funds but you are actually not rich. I'm not saying you are entirely wrong on what you think but it's clearly different because being rich what is required first is a change of status which starts from the very point that you are in to another level and another is accumulating wealth by making some long term investment plans, but sometimes a steady flow for years can actually amount to you being rich and it's simply depends on your patience, hardwork, consistency and investment aside this I'm not sure one can be financially free.
