Actually, recently due to extremely poor sleep, I've come to realize a very comfortable perspective.
If you can't sleep, just don't sleep; wait until you're tired to sleep, to prevent nervous breakdowns～
Taoism also teaches: follow your heart's desire.
A very simple yet useful principle: let go of obsessions.
Just like in trading, when you are constantly losing, don't think about revenge. Revenge is an obsession, "I want to get back what I've lost," "My judgment is correct; it's the market maker maliciously targeting me," "The last trade had some problems, this time I must follow the trend and it will surely be right"… and so on.
My recent insight is: there's no need to get entangled in past rights and wrongs; we only need to review past successes and failures. Then extract the parts that are beneficial to us. Let go of the remaining garbage.
Every subsequent time is a new beginning. After going through this cycle, your mindset will bring about different changes. You will also become more and more at ease.
