It's simple, but requires a great deal of time to take advantage of compound interest. It's simple, but it requires dedication: you must say the course. Invest early, invest often, and invest for the long term.

It is a happy realization, though, to recognize how simple it really is.

"Stay the course"... a key phrase. You must be a fellow Boglehead!

(Bogleheads have a handful of short phrases that describe the simple foundations of Bogle's investment philosophy. As you say, it's simple but takes time.)

Index funds, dollar averaging.

I call it "get rich slow."

Dollar averaging does not actually give you any benefits in an efficient market.

(But if your money trickles in monthly, you might as well buy monthly if there are extra transaction fees.)
