<i>Those paragraphs seem to me to basically say, &quot;Don&#x27;t bother if you&#x27;re not going to spend the rest of your life&#x2F;a very long time here&quot;, which I think is effectively saying &quot;don&#x27;t bother at all&quot; to most folks.</i><p>Maybe that&#x27;s the point. People who want to solve complex problems need to be committed. Not for a few months or a few years, but maybe lifetimes. Because that&#x27;s what&#x27;s required to properly solving something.
