It’s Wednesday today, let’s talk about technology. I’ll introduce several AI tools I frequently use and the reasons for choosing them. First is Cherry Studio, let’s look at a screenshot:

Yesterday I introduced the MECE principle, reviewing the “Mutually Exclusive, Collectively Exhaustive” approach to problem analysis. Today I’ve had a major breakthrough!

I vaguely felt that the content or format of my public account needed adjustment, as the content was too miscellaneous, with many ideas to express but never clearly articulated. When discussing this feeling with a colleague today, they suggested I focus on specific themes for my writing to make it more focused. Another friend who has updated their public account daily for over 2 years advised reducing the investment cost of daily updates to make it easier to persist.

When we feel someone is rambling, talking for a long time without expressing a clear point, or simply going along with others’ opinions without forming their own, we often say they “lack logic.” But what exactly is logic? How can we make our thinking more organized?

I remember in 2018, I heard a statement in “Fu Peirong’s Western Philosophy Course” on the Dedao App: “Logic is the rule and order of thinking.” This explanation is simple yet clear, using three words - “thinking,” “rule,” and “order” - to explain the abstract concept of logic clearly. But knowing the definition isn’t enough; I wanted to know: What are these rules? How do we establish order?

From DeepSeek’s strong launch at the beginning of this year to the subsequent upgrades of international models like OpenAI, Claude, and Google, AI capabilities are getting increasingly powerful. My personal feeling is: “Things I couldn’t do before, I can do now; things I didn’t want to do, AI can do for me.” In the end, I not only have to keep up with the pace of technological iteration but also supervise the quality of these large models’ work. Technology updates and iterations, far from reducing my workload, somehow make me feel busier than ever.

The “rustling sound” in my ears takes me back to my childhood. After many years apart, I’ve returned to using a buckwheat hull pillow.

A few days ago, no matter how I adjusted my sleeping position, including the direction and height of my pillow, the soreness in my shoulders wouldn’t subside after waking up. The direct cause was certainly related to prolonged sitting, but lying on my pillow, I couldn’t feel any relaxation. The latex pillow seemed soft, but even after I tried adjusting my sleeping posture, I could still feel its stubborn resistance, preventing me from relaxing.

Yesterday, we discussed the gaps between people, and concluded that they stem from differences in thinking patterns and cognitive abilities. The root of these differences lies in our understanding of “concepts.” The word “concept” sounds abstract, but we use concepts every day—from everyday terms like “dog” and “table” to complex notions like “happiness” and “freedom” that mean different things to different people. Concepts are both tools for communication and the basic units of thought. Today, drawing from books I’ve read over the years, I’ll start with logic, move on to analogies, and explore how concepts break free from rigid definitions and flourish in our lives.
