&gt; Call it an exercise in eccentricity or futility, and you&#x27;d probably be right.<p>The art geek in me sees this &#x27;exercise in eccentricity or futility&#x27; a rather interesting activity. Yes, he walked every street, but as he said it himself:<p>&gt; Nothing is forever, though. I can only claim to have walked every street in this city at this moment in time. New streets are being built as I write.<p>He has only walked through every street in SF as they <i>currently</i> stand. His prize is ephemeral. Tomorrow, a coffee shop will open and he won&#x27;t have seen it. Heck, coffee shops probably opened in the timespan it took for him to finish his journey.<p>And yet, despite not being able to say &quot;I have seen everything in SF&quot; for long, he can still say &quot;I have seen everything in SF at the moment I saw them&quot;. While this may seem a little obvious or silly, it shows how every experience we ever have is unique to us.<p>I apologize for ending with a cliché but my only conclusion is that the we live for the journey, not for the destination. Because when we reach our destination - when we have finally seen every building in SF - we realize what we have seen is gone, and new things took their place.
