"I think diversification and all the stuff they’re teaching at business school today is probably the most misguided concept everywhere.
And if you look at all the great investors that are as different as Warren Buffett, Carl Icahn, Ken Langone, they tend to be very, very concentrated bets. They see something, they bet it, and they bet the ranch on it." - Stanley Druckenmiller
motto seems to be concentrate to build wealth diversify to maintain your wealth.
