This is ridiculous, the most important document? Really? Let's keep a big document of all the inane questions everyone asks me day in and day out because that is an efficacious use of my cognitive resources! This is exactly the type of article I would expect from someone selling information products.

It's called memory, journals, and mnemonics. If someone asks you something important, commit it to memory, journal it, done. There is no need to keep a doc of every single question and there is a great body of evidence that the most important document you can keep is a daily journal and an idea document.

Too much internet marketer speak. Too much proselytizing.
