My friend Chuck wrote today about keeping a record of the things we make. “I’m rereading Jon Lee Anderson’s seminal biography of Che Guevara right now,” Chuck writes. “I have been struck by how many details of Guevara’s life and the shaping of his ideology we only know because he wrote them down in his diaries from a very young age.” Chuck goes on to make a larger point about the things we make being worth saving, that people may enjoy looking at them years down the line: “May we all love our own work enough to preserve it like this.”
