We all have the painful awareness that, during our lifetime, we will not have time to read every book worth reading, to visit every place that fascinates us, to learn what we’ve always dreamed of doing, to play musical instruments and knit scarves. In response to this anxiety, we make lists; bucket lists. Things to do, things you must see, 100 movies to watch at least once. They help us keep track of the meaningful time, of the time that does not dissolve between library hours and scheduled meetings and meals and sleep, the time that crystallizes in scrapbooks and gleaming pictures, in timeless anecdotes and stories repeated over and over. Cornell has its own bucket list, 161 things to do.
