According to JM Ibanez:

1) Always bring a jacket, or at least wear something warm. I got one of
the worst cubicles in the room-- right under the aircon vent. And now,
I'm typing this while I'm freezing my ass off. And I'm shivering.

2) Keep a notebook to jot down stuff. Especially any expenses you incur.

3) Take note of when your breaks are. You might never get another chance
to go to the bathroom, especially if you're boss calls you to a meeting.
(Thankfully, I've never been called to a meeting. Yet.)

4) Lay low... showing off tends to get more work piled on you. ;)

5) Enjoy your work. :)
