Warren Buffett is a skilled investor who is studied, analyzed, and imitated by many.
But the "secret" to Buffett's immense wealth is simply how long he's been investing, writes Morgan Housel in his new book "The Psychology of Money."
"Effectively all of Warren Buffett's financial success can be tied to the financial base he built in his pubescent years and the longevity he maintained in his geriatric years," Housel writes in his book.
And if you invest money at the level of someone like Buffett, the results become "ridiculous, impractical numbers," Housel writes.
High returns are nice, of course, but they're difficult to come by and not the only way to build wealth, Housel writes.
