I am currently reading Natalie Goldberg's The True Secret of Writing. In it she describes an exercise in which she visited the same seat in the same cafe every day and wrote about what she saw. No more meaning or purpose than that. A pointless exercise.
She reproduces each day's writing in the book. At first I wanted to skip this section - to rush ahead to the next bit of instruction. The next bit that I could extract some practical benefit from. I saw reading her pointless writing as an even more pointless exercise. And yet... her writing has triggered memories, assumptions, insights, ideas for my work, thoughts about writing style.
Maybe we need to make just a little bit more room for pointlessness in our busy lives. Maybe even in our work lives.
