Everything I have worked out and written down. Most of it is testing, because that is the job that pays for the rest.

The study notes are interview questions I can answer out loud, and one goes up only after I have explained it back in my own words. The articles are whatever else I am working out, published before they are finished and labelled with how finished they are.

I have been watched by about 1.7 million people and never once asked any of them for anything. This is what I learned about why, and what I have not decided yet.
