I really appreciate your psychological/emotional perspective on trading. That said, when hearing you say during this video that you "shouldn't feel" frustrated, angry, sad, etc., my therapist training kicked in. I wanted to offer an alternative: that it's more likely that one (I know at least me) will feel some level of anxiety, to say the least, when the market goes into these momentary free falls. Instead of telling myself "No, don't feel that," which can lead to self-shame and perhaps a downward sprial that may lead to worse decision making in the market, I go a slightly more subtle route, akin to Buddhist psychology, where I engage what is called the Witness self (think of it as an emotionally detached noticing part of yourself) and notice those feelings (fear, anxiety, etc). This kicks off an internal alarm, kind of an "Aha! I recognize this feeling. Now let's not be a slave to it and make bad decisions as a result).
I see in your description above you took a similar approach to what I just said than what you said yourself in the video, which is what I suspect you meant by it all along: "If you feel fear, or frustration, or anger, or depression when price collapses like this, try and shift that feeling to excitement (contained of course, logical only)" I think when you said to shift the feeling, I may be describing the mechanism by which that feeling is shifted.
On a personal experiential level I had a curious excitement when all this was taking place, but then again, perhaps that's because I have the luxury of having invested in btc between 5.5 -7.5k.
Thanks again for your perspective and keep up the great videos!
