Everyday thoughts, discoveries, and passing notes, kept in their unpolished flow.
I've decided to first focus on making software for myself, using any suitable technology and platform. Take care of my own needs first. If others like it after it's released, then I'll think about making money.
"Benefit yourself first, then benefit others." This mindset feels more natural.
Using AI to learn new skills is extremely efficient.
Laying the foundation, explaining concepts, background principles, practicing solutions, organizing knowledge. This is my learning process.
Of course, the entire process requires your own guidance and organization, because everyone's thoughts and ways of thinking are different, so the overall effect and feeling will also differ.

Last night I looked into the basics of web3 and had some questions, so I asked GPT. GPT answered very well, and I plan to organize and record these questions and answers. I never had the habit of organizing knowledge before, always thinking that understanding at the moment was enough, but memory is unreliable, and it's not convenient to review or look back again. The overall effect is just like a chat log, with some unnecessary information mixed in, and I have no interest or value in looking at it again.
At first I considered Google Docs, Feishu, Tencent, but finally chose Notion.
I didn't use Google Docs, firstly due to network access issues, and secondly because formatting is not convenient enough. As for Feishu and Tencent, the problem is that as soon as I opened their official websites, I was turned off — they are all enterprise-focused promotions, which is intimidating. The common problem of these three is that they have too many features and complex interfaces. Although they are powerful, they are also very off-putting. What I want is: UI and interaction should be simple, clean, easy to get started, and convenient for me to organize text and knowledge. Don't increase my learning and usage cost. I just want to use it intuitively without thinking, and quickly get my work done.
Lei Jun is probably the Chinese entrepreneur who embodies Japanese-style entrepreneurial spirit the most. He is a strong learner, willing to show vulnerability, and unafraid of adopting a humble stance.
The essence of Lei-style marketing is not in the numbers or fine print, but in the courage to be sincere and the bravery to face imperfection and temporary setbacks.
I am not a Xiaomi fan, never have been, yet I would not mock Xiaomi—a company that dares to acknowledge its gaps and strives to catch up.
On March 16 this year, I picked up my WeChat public account again to publish articles and images. The last time I posted was on March 28, 2020, and it had been abandoned for six years.
If I had spent those six years cultivating a public account, that persistent writing would itself have been a harvest.
Six years ago, I had no awareness or understanding of the compounding effect of time. Over these six years, my family has gained a lot—we've traveled many places and seen many sights. But I haven't felt much personal growth or accumulation. Many times, I just thought about things in my mind, took in a lot of input, but never produced any output.
Learning, practicing, and producing output form a good closed-loop learning path. I believe this loop should not rely on self-discipline or persistence, but rather on recognizing it as a scientific method worth adopting.
Now, I write down the thoughts in my mind. In the past, I used to think it was enough to just know something—writing it out seemed too troublesome, and what if I didn't write well? In short, various worries in my heart caused delays, and then nothing happened.
Recently, as I've been writing more, my habit has started to change: just write directly without overthinking, because words are so easy to correct and revise.
When I'm typing words, I quickly enter a calm state of mind, as if I'm having a conversation with myself, and time seems to disappear. Writing does take up some of my free time allowance, but isn't output itself also a form of freedom (freedom of expression)?
“Validate fast, fail fast” — I finally feel like I truly understand this mindset now, which is essentially the MVP approach.
My old process used to be: confirm the idea, choose the tech stack, build the architecture, design the UI, and dive deep into details. Most of my time and energy were consumed by the technical side upfront, rather than validating the idea itself or testing feasibility. In the end, many of those projects still failed. It wasn’t a complete waste, but overall it wasn’t an efficient way to build products.
Recently, I’ve started shifting my mindset and practicing the MVP approach instead. I focus first on validating the core functionality. If the product works and the direction makes sense, then I can refine and polish it later. This saves a huge amount of time and energy, while also giving me feedback as quickly as possible.
The time you truly control, and the lasting sense of ease and freedom you can sustain, are the best rewards you can give yourself.
