Just remember, without discipline, a clear strategy, and a concise plan, the speculator will fall into all the emotional pitfalls of the market - jump from one stock to another, hold a losing position too long, and cut out of a winner too soon, for no reason other than fear of losing profit. Greed, Fear, Impatience, Ignorance, and Hope will all fight for mental dominance over the speculator. Then, after a few failures and catastrophes the speculator may become demoralised, depressed, despondent, and abandon the market and the chance to make a fortune from what the market has to offer.
