Kardec Trader credits journaling with saving his trading career. After losing three grand, he'd chase the loss with bigger positions and lose six grand more. Journaling made him see the pattern.
The biggest thing that actually helped me was journaling. This week was rough. Why was it rough? What was I thinking? What was going on in my mind? How can I improve? How can I make it better? And just being aware of my thought process. Because a lot of times what would happen in the past is, let's say I have a bad week, I lose three grand. Now, mentally, I would be like, okay, I lost three grand. I need to make it back. So the next day, I would take on a big position that I wouldn't be comfortable with. Now, instead of making money, I'd lose six grand. I would never really be consistently growing.
