Start with what people ask you to notice
Someone sends you a brief because you can spot what is missing. A colleague asks you to look at a proposal because you notice a difficult assumption. A customer asks the same question again because your explanation makes the decision easier.
These moments are worth collecting. They are evidence of what people already find useful about your judgement. They can also be a better starting point for content than a list of trending topics that happens to sit near your profession.
Keep the credit attached to the idea
Naval Ravikant uses the term specific knowledge for expertise developed through individual curiosity and experience that is difficult to package into a standard training path. My Lazzzy Hustler essay explores that idea. The concept is his; the content application here is my way of putting it to work.
The useful question is not whether ordinary training matters. It does. The question is what you have learned to distinguish after applying the skill in real situations. Two people can know the same process and notice different risks, tradeoffs or opportunities inside it.
Turn a distinction into an explanation
Imagine a designer reviewing two landing pages. Both are tidy. Both use good typography. The difference the designer notices is that one asks the visitor to choose a service before explaining who it is for.
A useful piece of content could show that sequence, explain why the choice arrives too early and demonstrate a clearer order. The example is hypothetical. Its value comes from exposing a decision the viewer can inspect, rather than asking them to accept a broad claim that the designer has good taste.
Build an evidence notebook
Keep a small record of questions, recurring misunderstandings and decisions you have had to explain. For each one, write the situation, what you noticed, the choice you made and what information could have changed it. Record limitations along with the lesson.
Use only material you have permission to share. If a real example contains confidential details, build a clearly labelled fictional demonstration that preserves the decision without pretending it is a client result. Specificity does not require publishing someone's private work.
Let the audience test your explanation
Choose one entry and turn it into a small demonstration: a before-and-after comparison, an annotated example or a walkthrough of a decision. Give the viewer enough context to understand when the advice applies.
Then pay attention to the response. A useful follow-up question may expose an assumption you forgot to explain. A reader's different situation may reveal a limit. That feedback gives you the next lesson and makes the body of work more precise. Your knowledge provides the starting material; communicating it well is a skill you keep developing.
