Job offer came in! - any advice?

They called on Friday with an offer and I said yes right away. I am in Cleveland, in case local advice matters. I am relieved and a bit nervous. Any advice for starting over?

Congratulations! Take notes on names and processes in your first week. It helped me settle in.

Thanks for writing this out. I went through something close to it 13 months ago, and it settled down once I kept a simple log of every call and form.
