There's an urban legend that Albert Einstein once said compounding [interest] is the most powerful force in the universe.
Whether or not he really said it, that line has become my financial motto. I strongly suggest you adopt it.
When asked to name the greatest invention in human history, Albert Einstein simply replied "compound interest."

But did the eminent physicist really ever say such a thing? The claim that he did appears dubious for a couple of significant reasons:
- The attribution of this sentiment about compound interest to Einstein doesn't seem to have existed during the scientist's lifetime, first appearing in print only several decades after his death, and always repeated as something he supposedly said in some indefinite time and place. (Albert Einstein died in 1955, but the earliest mention we could find of this item was in a 1983 New York Times blurb.)
- Just what Einstein reportedly said about compound interest varies quite a bit from source to source: That it was "the greatest invention in human history" (or "the greatest invention of mankind," or "the greatest invention of all," or "the most significant invention of the nineteenth century"), that it is "the most powerful force in the universe," or that it is "more complicated than the theory of relativity." (That last variation echoes another sentiment popularly attributed to Einstein which also began to appear only well after his death, to the effect that "preparing a tax return is more complicated than relativity theory" or "the hardest thing in the world to understand is the income tax.")
