You will wrestle the hardest with the desire to make more, right after your model performs as you expected it to.
The profit you aimed for, the setup you executed on, the proper lot size used... allowed you to trade it impeccably.
That boring task baits impulsive behavior.

You forge discipline by refraining from extra.
Your trading must be boring, routine & devoid of emotion.
When you master yourself & this, your trading will be absolutely insane.
Prove me wrong... try it.
