I bought an external hard drive not long ago, and transferring a lot of my bulkier files (photos, some music, etc) onto it enabled me to free up some serious space on my actual computer. My nice laptop works much, much faster and more happily now than it has in quite a while.
I feel like there’s a similar process happening to my brain right now, as I figure out which mental files from the past semester can be offloaded to some other place.
