Hello, I'm Jian Yang.

I write about investing, software, books, cooking, and other things that interest me.

This site serves as a public journal to document ideas and capture insights. By putting them into writing, I hope to further develop these concepts and look back to see how my understanding changes over time.

Etic v Emic

Emic is an insider’s view of a culture, while etic is an outsider’s scientific view. [1]

This is important for all market research. We need to think from the customer’s point of view.

Marketing has to address a concern or motivation that already matters to the target audience. Most don’t bother with how clever a solution is.

Horses, Cars, and AI

Many people use the fear of over-reliance as an excuse to avoid learning how to use AI properly, treating those who do with disdain and contempt. I disagree. That’s equivalent to saying we shouldn’t use cars because we will lose the skillset of taking care of horses.

I believe we should embrace and adapt to new technologies as they come, while being mindful of the downsides and using the latest technology to help us get better at achieving our goals in life. Back to the horse and car example, our goal is to get to our destinations, not to be overly competent at a sub-optimal alternative.

The Variant View

One way to think about why a stock will appreciate in price is that everyone has different expectations of the company’s future growth.

The variant view of a successful investor is being able to stand independent of the market, identify a company whose future growth as determined by the consensus is wrong, and arrive at a more accurate analysis of the business.

In other words, it is akin to identifying a money printer that prints $10 every time when everyone else thinks it only prints $5. You do not just need to find a good business; you need to find an expectation gap where you are both different and right.

Why, What, and How

Differentiating the why, what, and how:

  • Why: We need energy to go about our lives.
  • What: We need to eat food to get that energy.
  • How: Find a recipe, buy the ingredients, cook the meal, chew, and swallow.

Time is the Currency of Life

I found this on Reddit today:

Time is the currency of life

After first 2–3 millions, a paid off home and a good car, there is no difference in quality of life between you and Jeff Bezos. Both of you have limited amount of time on earth — you have twice if not more than Jeff, so you are richer than him. A cheese burger is a cheese burger whether a billionaire eats or you do.

Money is nothing but a piece of paper or a number in your app. Real life is outdoors.

Become financially independent that’s usually 2–3 M. Have good food. Enjoy the relations. Workout and enjoy sex. Sleep well. Call your parents. That’s all there is to life. Greed has no end.

Repeat after me. Time is the currency of life. Money is not.

Sooner you figure this out, happier you will be.
