If you are starting a new situation today, do not put pressure on yourself to be a superstar right off the bat. You need to give yourself all the time you require to get a handle on your new routine, new environment, or the new group of folks around you. The empathy that will be shown you today will encourage to relax and just be yourself. There is a freedom in letting go of the expectations you put on yourself. Your job today is to learn, not to impress.
