The littlest things are the funnest.

Choosing a pen to sign the documents with (the Pilot Precise V5 RT rollerball, guaranteed to make you feel authoritative).

Choosing stamps for the envelope containing the documents you've just signed (two Wendell Wilkie 75s, two Samuel P. Langley Aviator 45s labeled "US Airmail," and a Frank C. Laubach 30-center).

Making a label for your new hanging file, "book contract," when you're too excited to get the lettering centered on the label, too excited to care.
