Oliver Burkeman writes about professor Robert Boice’s attempt to get PhD students to work a little bit daily and take weekends off. The students wouldn’t do it and their desire to rush the work actually got in the way of their progress. I found something similar when I did a dissertation boot camp where for the whole day I was working on my dissertation instead of the small increments that I normally did. I was so exhausted after that week of pushing really hard that I had to take a 2-week break which obviously did not advance me as far as you might hope a boot camp would.
