Currently in the throes of attempting to trade for a living.
What has helped me immensely is to ‘denature’ goals so that I can measure success beyond something binary like “did I achieve X”. Instead, I will specify more subtle signs of progress/improvement, and track those instead. That way, even when I fall short of the ideal outcome, I still have actionable, helpful takeaways that can assist w/ my next attempt. Repeat ad nauseum until success.
Another suggestion is to read books like ‘Grit’ and ‘Resilience’ and ‘Mindset’.
