Why Great Founders Can Be Poor Investors
- Entrepreneurs often become mediocre investors because business success is typically a one-in-10,000, power-law outcome not easily repeatable as an investor.
- Michael Sonnenfeldt contrasts the power-law of entrepreneurship with the bell-curve of investing, urging a shift to preservation after an exit.
Sticker Shock After Selling A Business
- Selling a cash-flowing business often produces 'sticker shock' because sale proceeds invested conservatively yield far less annual income than prior business cash flow.
- Sonnenfeldt warns owners to plan post-sale lifestyle and cash needs before selling.
Ruthlessly Cut Fees To Protect Compounding
- Minimize hidden drags like fees and taxes because small differences compound massively over decades.
- Sonnenfeldt illustrates that a few percent difference (10% vs 21%) turns $1 into $75 versus $3,000 over 43 years.
