From Edwin Lefèvre (1871–1943), American journalist, writer, and diplomat most noted for his writings on Wall Street business, Reminiscences of a Stock Operator (1923):
The sucker has always tried to get something for nothing, and the appeal in all booms is always frankly to the gambling instinct aroused by cupidity and spurred by a pervasive prosperity. People who look for easy money invariably pay for the privilege of proving conclusively that it cannot be found on this sordid earth.
Anyone who read this book should realize the author was a fraud, a man who played all the angles, and after 1929 blew his brains out after losing another fortune in the crash.
So take it from a man who ought to know and who paid the price.
