Critical thinking
Critical thinking is critical.
There are 2 sides of everything. Learning that it's 6 from one side, but 9 from the other side.
I learn to think, like how Derek write. One thought. Then think against it. Repeat. Distill the essence.
I learn from "Thinking, Fast and Slow" by Daniel Kahneman. Good book, but currently, I'm not ready. I didn't finish it, but will go back to it when I'm ready.
BBC has a great short video on critical thinking.
I believe society will improve significantly when more people learn critical thinking.
Not accepting thing as is. Able, and willing to process thoughts. Take the more difficult path. Check facts, confirm.
It's a crucial skill.
Is it above every other skill? At the moment, I believe it is.
