9 things you need to do in your 20s that will make you a millionaire before 30 – #4 and #8 is a must
One way to earn more is to increase your streams of income. In author Thomas C. Corley’s five-year study of self-made millionaires, he found that many of them develop multiple streams of income: 65% had three streams, 45% had four streams, and 29% had five or more streams. These additional streams include real-estate rentals, stock market investments, and part-ownership in a side business.
“Three streams of income seems to be the magic number for the self-made millionaires in my Rich Habits study, but the more income streams you can create in life, the more secure will your financial house be,” he writes.
