Trading Week Preparation

My usual trading system continues to fail, what should I do?

If a trading system built by myself often fails and causes losses, should I abandon this system and replace it with another one? Is there a stable and profitable trading system?

What would you say to yourself if you went back to your first day in trading?

What should I do if my trading system encounters a retracement?

If you have a bad mentality, does this mean that you are not suitable for trading?

I resigned yesterday, due at the end of the month, I want to do trading full-time, but I don’t know how far this road can go?
