The key is not pissing of the people who are trying to help you, while you are frustrated!
I so agree Neato, but it is very, very difficult in my case. I am sure that I have gotten both P and VP angry over the last few years. Part of it is the fact that I want things done right away, part is the fact that English is my second language and because of the lack of words (when I am excited) I frequently come along as impolite. At least I think so

But look, even if I sounded angry and impolite, it has worked.
