Nice of her not to divulge the science of it and just say it's a lot of iterations.

That would not make me hate writing less.

Didn't sound like any science was involved. There were no observing, hypothesizing and testing steps to be found. Can't have science without those.

Science is like that too, it's mostly very tedious and repetitive work.

With a little practice you too can write a short essay on an interesting topic while not actually saying anything meaningful or useful!
