I&amp;#x27;m in math and there are a number of people in math who also say four is the limit; a quick google found this for example  &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;theweek.com&amp;#x2F;articles&amp;#x2F;696644&amp;#x2F;why-should-work-4-hours-day-according-science&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;theweek.com&amp;#x2F;articles&amp;#x2F;696644&amp;#x2F;why-should-work-4-hours-...&lt;/a&gt;.  FWIW.&lt;p&gt;Also well-konwn are the first two paragraphs of Littlewood&amp;#x27;s Miscellany, &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.gwern.net&amp;#x2F;docs&amp;#x2F;math&amp;#x2F;1986-littlewood-littlewoodsmiscellany.pdf&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.gwern.net&amp;#x2F;docs&amp;#x2F;math&amp;#x2F;1986-littlewood-littlewoodsm...&lt;/a&gt;, p 189.</text><parent_chain></parent_chain></comment><story><title>The Role of Deliberate Practice in the Acquisition of Expert Performance</title><url>https://acesounderglass.com/2019/06/21/epistemic-spot-check-the-role-of-deliberate-practice-in-the-acquisition-of-expert-performance/</url></story>
