Emotions are not the enemy of consistency.  
Emotions exist to bring consistency to all of your beliefs.  
Emotions arise automatically based on the beliefs you hold.  

You consistently break the rules and consistently obsess over winning and losing.  
This is because you hold the belief that "winning and losing have value" over following the rules, and your emotions work to make you act consistently with that belief.  

If you truly understand from experience that following the rules leads to profitability and transform this understanding into a belief, your emotions will work to help you act consistently with that belief.  
You will become a trader for whom consistently following the rules is easy.  
When you attempt to break the rules, your emotions will create a strong sense of resistance, making it difficult for you to break them.  

This is not a matter of emotional control, mental toughness, or eliminating emotions.
