I talk a lot about having multiple streams of income. I believe it’s the most efficient way to build wealth–but I’m not the only one. Researchers have even pinpointed a statistic: millionaires, on average, have not just one, but seven streams of income.
As with all investments, I believe that it makes the most sense to diversify your streams of income. That is, up to a point. If you’re finding a category that works for you, then go for it.
