Time is your friend, impulse is your enemy. Take advantage of compound interest and don't be captivated by the siren song of the market.

You could take all the gold that's ever been mined, and it would fill a cube 67 feet in each direction. For what that's worth at current gold prices, you could buy all -- not some -- all of the farmland in the United States. Plus, you could buy 10 Exxon Mobils, plus have $1 trillion of walking-around money. Or you could have a big cube of metal. Which would you take? Which is going to produce more value?

Investors can only earn what companies themselves can earn; the government or the markets themselves don't kick anything in. How can you get anything more out of a farm than what it grows?
