Because I'm going to tell you something you won't hear from most traders:

"Professionalism doesn't mean you don't lose... it means you aren't surprised when you do lose."

Professionals aren't magicians... they are people who have built a system that allows them to endure losses without their lives falling apart:

They distribute risks like someone building a dam.

They treat loss as a necessary bill.

They know that a black day will come... so they store hope like food in winter.
