The attention it still takes

What it is
Roughly how many hours a month the product still needs from you.
Why it matters
A product is meant to break the link between hours and income. Often it does not — packing, replying, chasing suppliers. Counting the hours tells you whether you own a product or a job that sells objects.
The method
Estimate the monthly hours honestly. If it is close to a full working week, the line is not yet doing what a product is supposed to do.
Example
Adeel spends about 60 hours a month on his. On PKR 69,000 that is PKR 1,150 an hour — good, and worth knowing rather than assuming.

Now you

Hours a month this takes from you. Zero is a valid answer if it is true.
