Orwell's 6 rules for writing - which ones do you break?

Many students are now writing their final assignment for the year. Some students are studying for their upcoming exams and some students are crazy enough to be enrolling in Summer units!

Here are some writing tips from George Orwell's 1946 article on Politics and the English Language.

The key points from this article:

1. Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
2. Never use a long word where a short one will do.
3. If it is possible to cut a word out, always cut it out.
4. Never use the passive where you can use the active. (click here for explanation)
5. Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
6. Break any of these rules sooner than say anything outright barbarous (in other words, use common sense when applying these rules)

I'm guilty of breaking all of them and I have found that to not break them, I need to continually practise what I call the Art of Writing.

What 'rules' do you break when writing an assignment?
