If we can remember that there is no writing in general and no magic formula that will help us write well in all situations, we are more likely to be able to use (or transfer or repurpose) what we know effectively from prior writing situations
It is very important to remember that learning to write in general is not realistic and that writing is about audience and setting. Teachers that teach students one certain way to write are not setting them up for success and if they continue to teach them this way of writing, students will never learn how to truly write.
