I agree to most of them, execpt these ones:

Sigh loudly when there are many people around, giving the impression that you are under extreme pressure.

If you sigh loudly, people know there must be something you cannot solve or have problem with.  You should show you are competitable to handle anything.

Always try to look impatient and annoyed to give your bosses the impression that you are always busy.

We should look patient when listening to the boss even we are busy.  If you look impatient, the boss might think you do not like his idea or listen to whatever he is saying.
