I found this article to be an object lesson in living well. It's not an instruction manual, but rather a warning. When your stock in your company shows your net worth at $50 million? Yeah, sell it.
Sell it while you are ahead.
I mean, really! These people have 2-5 million dollars in the bank, and are lamenting, "Oh, poor Charlie, he'll never be able to retire." What? Poor Charlie? How about poor Public School Teacher, who has a negative net worth, and will never be able to retire? She'll fall dead on the floor in the middle of class.
Poor Charlie? In his million-dollar home in Silicon Valley?
