source of income

best source of income to become rich quickly, I wouldn't know. the best source of income to keep going rich would have to be passive income though meaning you can stop working and still get paid for your past efforts. I think the best source of income is commissions in insurance if you mean actually working for it. Get a high-paying client buy an annuity and you can get an instant 500,000k to one million dollar check right then and there. of course real estate is good but you usually have to wait 5-6 years.
