Here is further academic counteradvice: the reason I dislike academic advice is that it is about speed, about how to wring more out of the day and out of yourself.
I just spent about three hours revising someone’s M.A. reading list, formatting it, sending it off, finding their question (I had written it, but could not find it), revising it, formatting it, and sending it off. I wasn’t being slow or over-careful, it is just that this is really how long it took.
Before I started, I spent almost two hours avoiding starting. I did not want to start because I knew it should take under an hour, or under half an hour. I would have to rush to make it in that time and it would be most unpleasant. So I would not start.
I was only able to start by deciding I would allow the task to take the time it would. Then it was not difficult at all to begin, since I was not about to have to undergo the extremely unpleasant stress of rushing.
Because of the exhortations about doing things in half a hour or less, it took me five hours to do what could have been done in three.
