I start a new job on Monday - any advice?

I start on Monday after a long search. I am in Seattle, in case local advice matters. I could not have done it without this community. How do you handle the first week?

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.

So happy for you. Thanks for giving hope to the rest of us.
