It&#x27;s a bit of selection bias though, isn&#x27;t it?  It seems like you&#x27;re bad at only having one thing to do, but it&#x27;s likely that by the time you only have one thing left, that very thing is what you&#x27;ve been putting off the longest.  And you may have been putting it off for a reason (you don&#x27;t want to do it, it&#x27;s hard, it hasn&#x27;t been thought out, etc.)
