Most traders trade their emotions , the minute they open the screens , their emotional brain calls all the shots and traders can become undisciplined .The emotional brain (amygdala ) is faster than their rational brain , it is the brain that sometimes does not function correctly for traders
If you believe in yourself and have dedication and pride - and never quit, you'll be a winner. The price of victory is high but so are the rewards. Paul Bryant
I like this one: "Jack of all trades, master of none." It's always better to concentrate on something than to do everything at the same time.
