How to give enough value without giving away the product

I was reading Nika's thread here about free vs paid features. Really made me think.

( shout-out to @busmark_w_nika ! )

She talks about giving generalized advice for free, but charging for specific, tailored help. That's a good framework.
But most product owners figure this out after they build, not before.

That's backwards.

Since the rise of AI, do you feel that your job is at risk? And what about certain professions?

When AI entered the public stage in 2023, I was working as a copywriter. One client gave me a condition:

either I write more articles using AI for the same price
or I lower my rate per article

That was when I realised this job was starting to change significantly. (And I ended up.)

I read 16 IRS publications from Korea to build a tax app. Here's what broke my brain.

I read 16 IRS publications from Korea. Then I found several government audit reports from the GAO. Here's the number that stopped me cold.

I am not American. I've never filed a Schedule C. I've never spoken to the IRS.

But I was already building a product for 31 million U.S. self-employed people. So I needed to understand their tax reality.

16 IRS publications. Multiple audit reports. Hundreds of pages. One month.
