Traders should understand that their behavior as a person will reflect on the kind of trader they become.
As a person, if you are Disorganized and inconsistent with your decisions, you will be a disorganized and inconsistent trader.
If you are not a disciplined person naturally, you can't be a disciplined trader, you will hardly follow your plan.
I have seen people who said trading has helped them become a better person, the truth is they saw potential in trading so they improved in themselves as a person and it affected their trading life.
You have to be disciplined as a person to become a disciplined trader.
