The market is always right–except at significant tops and significant bottoms.
Keep and open and flexible mind. When in doubt, get out.
If you must have a guru, take him or her with many grains of salt
Do not add to losing positions.
Try every day to make yourself stronger, better and more integrated as a person.
Stay true to yourself. Lying to yourself and others, and trading on hope and prayer do not work
Most importantly, accept and recognize that you are not perfect. You are human and are going to make mistakes. Trading is the only profession where losing is actually winning. BUT— unless you accept mistakes as mistakes and learn from them, you will not progress and be upside down. Unless you are able to get your trading brain out of the cave you will not accumulate regret. It is only through the true acceptance of a mistake as a mistake that we accumulate regret. This is how we learn and grow as traders and human beings.
