Here are some of my thoughts, which might be wrong or incomplete, and I welcome discussion on them.

1. Answer Two Questions a. What to do? Some companies are very good at this, like Anker, which decides what to do based on market growth data. b. How to do it? DJI is very good at this; as long as you know the direction, you can generally make the product perfect.

2. Curiosity and the Unknown a. Maintain curiosity, think about any product around you, how it came to be, and why it was designed this way?

3. Simplicity and Complexity a. There are no simple products in the world; all great products become more complex because they cover a wide enough user base and demand is sufficiently dispersed, like iPhone, Mac, DJI, Tesla, NVIDIA. b. However, to break through, the product must achieve the following two points: 1. Easy for extreme users to use. 2. Easy for beginners to get started, which is the most difficult, possibly involving many technical changes/breakthroughs.

4. From Extreme Products to Beginner Products a. You may bear a heavy burden and often be killed by emerging technologies. b. From Beginner Products to Extreme Products 1. You may face many technical challenges, requiring a lot of money, and in the end, you may not even be able to make the product, dying on the way to entrepreneurship/product development.

5. Delve into the Details a. The core of the founder model is a simple principle: focus on details. b. You must understand what the product looks like; if you don't understand the details, the product will be out of control. c. The best way to delve into details is to become a qualified test engineer, different from a test engineer, you need to test from the user's perspective.

6. Know Yourself and Know Your Enemy a. Know yourself, communicate more with R&D; product managers are the leaders in battle. If you don't know your soldiers' abilities, strengths/weaknesses, weapons, and likes/dislikes, how can you lead them to victory? b. Know your enemy, who your competitors are, how many people they have, how many years they have been in business, what their strengths and weaknesses are.

7. User Behavior a. How to judge whether your product is good or not? 1. Give your product to users without saying a word, observe their actions, expressions, and operation time when using your product for the first time. 2. Both software and hardware products are applicable.
