It's been a big week on behavior... You have to be willing to feel all your feelings around trading. What might be holding you back from great success could be your reluctance or lack of willingness to feel new feelings around techniques or trading styles that are different from what you're currently doing.
Go back and listen to the "Rituals and Routine" episode. You might understand a trading technique or style intellectually, but you don't know it thoroughly until you've experienced it emotionally and psychologically.
Ed Seykota taught me that "the feelings that I don't want to feel have as much power over me (my trading) as the ones I do want to feel."
When you are willing to feel all your feelings, none of them can control you. They are all trying to teach you something. Are you open to listening at least?
You can test a new system (feeling) with 5 or 10% of your capital. If you trade enough, you'll realize that certain trading styles and techniques are there for the sole purpose of generating the emotions you are willing to feel, even if the trading strategy is an economic bad - day trading, for example.
You might be married to your current methodology not because it's the best one for you, but because you like how executing it feels. I suspect this is how most aspiring day traders feel.
You get to hang out with other guys, talk shop, have a sense of community, yet practice a belief system around trading that is not effective for long-term success.
