Despite his track record, Bill Harris bootstraps his new company with his own money. The primary benefit isn't avoiding dilution; it's the freedom to pivot in the early stages without the administrative and psychological burden of constantly justifying strategic changes to a board and investors.

While diversification is preached for managing risk, the world's most successful investors build wealth through concentration. They make a few large bets in areas where they have a distinct advantage or "alpha," rather than spreading their capital thinly across the market.

In your 40s, resist diversifying into areas you don't understand. Instead, invest 70% of your capital into your core area of expertise where you have an information advantage. Allocate 20% to adjacent opportunities and only 10% to "moonshot" ventures outside your competency.

Protect your core business by never overextending it operationally; always maintain financial discipline to ensure its survival. Separately, be willing to take massive, "bet the farm" risks with personal savings on asymmetric investment opportunities, even if it means liquidating everything.

To navigate the power-law dynamics of consumer investing, firms can use a barbell strategy.
