"By borrowing from the training techniques of the musician, the prospective master of any other elemental life-sustaining activity, such as speculation, can walk with the gods and stand with giants."
(Niederhoffer, The Education of a Speculator, p. 339)
As a student of virtuoso (electric) guitar, I appreciate Niederhoffer's attempt to connect instrumental practice with trading practice. There is cacophony (to my ears) in his stringing together of notes (and, I've omitted some that had harsh distortion), but the movement is overall sonorous. 🎸
