Anek talks of the need for a positive metal attitude in trade "Winning attitude. A positive mental attitude is essential to succeeding over the long haul, and my definition of a winning attitude is a positive expectancy from our efforts. Take a moment before the trading day begins to see yourself making all the right decisions, waiting for the market to come to you, striking at the correct moment, etc. It's a good way to increase your focus and get into the 'zone'."
The attached article is on Self Belief in Sport and NLP, it discusses many things that a trader can benefit from. Try the NLP exercise over a week at least. Find a relaxed quiet position do some deep breathing/meditation etc then start... when you find your trading, discipline, attitude slipping in the future return to this exercise. Tailor the routine to what you are trying to improve.
Also note the paragraph "The average sportsman tries not to worry as he/she thinks about what is at stake and the potential consequences of failure. The ability to deal with failure can heighten or hinder your belief in your ability and learning how to deal with it should be taught at an early age as failure is an integral part of sport. How it is handled can be the most important determinant of how successful an athlete becomes. Baseball players experience massive amounts of failure, even the elite players find that 70% of their efforts end in failure."
You realize the importance of this when you see that most traders have a low win loss ratio (< 50%).
Anek - Key to trading is entering wisely, cutting losses short, letting winners run, sounds like a cliche, but that's really all there is to it.
