Hi zinniagirl...
Get psyched! I do that every time i have an interview or anything of the sort... i get psyched by doing some online research!
Take some time and do research on the company that's interviewing you, i always find that if you manage to squeeze in some knowledge about their company or the person doing the interview, it's always a plus, shows them you've been doing your homework!!
You can also research tips on how to handle an interview, you probably know all there is to know but hey... sometimes just reading through stuff like that gets you excited about it and who knows, you might get some ideas!
Good luck with the vacuum!
Ann
