Confession: I am guilty of this. Well, sort of. I actually did write a book, and it did sell more than 3 copies, and now I put &quot;best selling author&quot; on my resume, on account of my book being #1 in its category (sometimes) and #1 on oreilly.com (sometimes).<p>So far no one has gotten bent out of shape about it (or maybe no one has looked at my resume), I assume because they&#x27;re smart enough to know that a &quot;best selling&quot; data science book is not on the NYT list outselling Stephen King and 50 Shades of Gray and Hunger Games, it&#x27;s bestselling among &quot;Books &#x2F; Computers &#x2F; Data &amp; Data Analytics&quot; or whatever.<p>Having put my bias on the table, I have a hard time getting worked up about what this guy did, for the following reason:<p>&quot;Whoa, you&#x27;re a bestselling author? What did you write?&quot;
&quot;It&#x27;s not a book, it&#x27;s a picture of my foot.&quot;
&quot;Oh. That&#x27;s kind of strange. How many copies did it sell?&quot;
&quot;Three.&quot;
&quot;...&quot;<p>I mean, it&#x27;s not like there&#x27;s some kind of special club where &quot;best selling author&quot; allows you to cut in line or anything. Is there? If there is, please let me know.
