Hey congrats! whatever happens i'm sure you will learn from it. my suggestion first is never talk about religion, politics, or sports in the office even if someone tries to draw you in to a conversation about them. the problem is that you can say something even innocently which can change someones opinion of you forever, and then later stall your work progress.
on a more positive note - if people go out of the office for lunch - then make a point of asking and going to lunch with different people. a little bit of personal time with people outside of the office can really make a huge difference long term. you also might make some new friends. there is also no harm in asking your manager or direct boss to have lunch with you.
