Amen! Have big ears and a small mouth. Think of yourself as an anthropologist among a herd of CubicleChimps. Your main goal is to observe and learn about CubicleChimp behavior. You are not there to overhaul their social structure, otherwise you wouldn't be an anthropologist.
Later on as you gain more experience with people, the domain (line of business), and machines, you'll get a valid chance to make changes. But don't rush that step. You first have to let the CubicleChimps accept you as a valid member of their herd. Otherwise, the alpha people (not always males) will put up barriers and jab a horn into your rump*.
And, learn to go with the flow. When in Rome... accept for the lazy parts. It's not good for newbies to copy lazy organizational behavior. If you show you can copy the good parts first, then they'll later cut you some slack.
I remember traveling with a seasoned employee early in my career, and I copied some shortcuts he used on his travel expense report. The Expense Dept. didn't like it one bit and I took heat for that. My boss fortunately patiently explained to me that the seasoned employee gained enough trust to take shortcuts. I had yet to pay my dues.
* You can be a know-it-all newbie jerk at work, but you'll have to accept a pay-cut to be allowed to be that way. You're essentially paying an asperger-social-skills tax, which is about 10 to 20% off what an amiable employee would get in the same position. (There are exceptions for high-demand specialties/fads.)
