No, Greed is the real killer. Look at most newbies questions on this site and others, you will soon find questions along the lines of "How do I make a lot of money as quickly as possible? Which strategy never looses?"
Come on, would you allow a guy or gal to operate on you who has only read some book on "how to preform surgey 101?" Of course not!
Newbies don't understand, people in this industry have spent many years and money sharping their skills. To think you will be on the same level or beat us is very foolish.
