Job one in becoming a more resilient person is the constant work of making one’s mind more resilient. Could I really become more resilient when my mind is so fragile and I am so anxious? Yes, I can. As long as I can still learn new things. Otherwise, sadly, no.
I’m going through a few days at the moment where my mind is very fragile: anxious, brittle, scattered and unfocused. Perhaps there are times when you know the same.
When I realized what was happening inside, I went to reread something that works for me in fragile mind-states: a Taoist teaching called wu-wei. More below.

Tough times calls for tough people. Personal resilience begins with toughening our minds. See, in G's take on human biology, the mind supports the spine. A weak mind causes the spine to dissolve. My major concern with progressives is the mind-spine connection. Only hard work creates a tough mind. Our minds are plastic: life will mold it for you if you don't construct it through will, hard work, perseverance. OK, there's work to do. First principle: modern ethics (along with all of modern philosophy) is bullshit. Classical times was tougher than our time. It produced tough-minded people. The classical world followed virtue-based ethics. I follow them. Below is a summary I did for myself of Aristotle's Nichomachean Ethics. It explains the classical world's goal of life and I organized extracts of Aristotle's words into a coherent summary for my own use.
