"... the best way to think about investments is to be in a room with no one else and just think. And if that doesn't work — nothing else is going to work. ... what you are looking for is some way to get one good idea a year ... and then ride it to its full potential. ... Wall Street makes its money on activity — you make your money on inactivity."
