There’s a strong correlation between expertise and a commitment to get the basics right.

Warren Buffett is a perfect example of this.

He is arguably the best investor in the world, yet he said he would invest his entire estate into a simple S&P 500 Index Fund.

Why would he do this?

Despite his financial sophistication, he realizes that achieving the basics of “low cost” and “diversification” trumps all other considerations. 

The beauty is in the basics.
