Spurious nails it again:
[...] I am stranded in the office without being able to write anything for the book. What to do instead? write about what you cannot write, so at least you have some relationship to what needs to be done, even if it is only at one remove. Vicarious writing, writing by proxy: this is what blogging permits, as letter-writing used to do.
Once upon a time, I would have used this interval to have written to a friend. Such a writing seems very far away now. Remember the joy of criss-crossing letters: one sent to X and another received from X and so on, each with the two to three day wait which detached what was written from what was experienced in the moment of writing. But this is already naive, as if writing did not always demand such a detachment: as if to write and to write a letter was already to have lost what was experienced and to have regained it in a new way, as words on the page.
Now, instead, words on a screen. But this is happiness: the sense something was done, that I will have made something from these vacant minutes.
I have such admiration for those who transcend this.
