Yes, I finally decided that I should stop sleeping on the futon that I had bought used in grad school nine years ago.  And two nights of sleeping on the nice new bed has made me go &#8220;Wow!  Why did it take me so long to decide to do this?&#8221;  A good question.  One I actually thought about for a bit, and here&#8217;s my answer.<\/p>\n<p>It&#8217;s a matter of energy and attention.  We all have certain things that we don&#8217;t question in our lives, whether it&#8217;s our religion, our devotion to a given sports team (Go Cubs!), our affiliation with certain groups, etc.  We can&#8217;t question everything.  While I love the idea of always being able to pry open the black box to see why something is the way it is, I can&#8217;t always do that because it takes time and energy.  Most of the time, I have to just accept the black box as is, and use it.<\/p>\n<p>So I make a decision, and I move on, and I don&#8217;t question the decision any more.  Whether it&#8217;s buying a car or a new laptop or what software to run my blog on, I find something that works well enough for the moment and forget about it, leaving more of my time and attention for things I find interesting, like reading or thinking about what I&#8217;m going to write on here.  It&#8217;s a matter of conserving cognitive effort for things I care about.<\/p>\n<p>To give credit where it&#8217;s due, this idea is mostly stolen from <a href=http:\/\/www.paulgraham.com\/nerds.html>Paul Graham&#8217;s essay on nerds<\/a>, where he points out that most nerds are unpopular in school because being popular is a full time job (between choosing clothes, going to the right parties, etc.), and nerds don&#8217;t care enough to bother.<\/p>\n<p>So, in this specific case, every year or so I&#8217;d think about getting a new bed, and decide against it because I was sleeping fine on the futon, and a new bed is expensive.  Each year the futon was getting worse and worse and my disposable income was rising, and this year the lines finally crossed, I got the new bed, and it was so easy that it prompted this post of wondering why it took so long.  And that&#8217;s often the way it is.  <a href=http:\/\/www.nehrlich.com\/blog\/2004\/10\/07\/#productivity>My post about productivity<\/a> laments this aspect of myself, but I think it&#8217;s understandable in light of a theory of cognitive effort.  Or maybe I&#8217;m just making elaborate justifications.<\/p>\n<p>Oh well.  Given that this is the fourth post of the evening, I think I&#8217;m going to shut up now, turn off my brain, and watch my tape of the O.C. recorded earlier.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I bought a bed last weekend, and it was delivered two days ago.
