Some useful tips for your new job:

 Make a good first impression. Your first day will form the basis of what many of your colleagues think about you.
 Come into the work environment with an open mind.
 Handle your freedom. No one is going to stand over you with a time clock. People do tend to notice, however, if you are tardy, if you leave early, or if you take long lunches.
 Learn as much as possible early on the job. Take advantage of courses or workshops offered or financed by your employer.
 Watch and learn to handle office politics by watching your colleagues.
 Be polite. Follow the basic rules of conduct, courtesy, and appreciation. Don't forget to thank the colleagues who help you.
