I’ve had a lot of first days over the years. I’ve had productive and positive ones, stressful and disorganized ones, even flat out boring ones. In fact, I finally had my best first day this Monday. Most of the time, the tone of your first day is set by those in charge of onboarding you (which could be anyone from the Head of HR to an intern), so you don’t always get to choose the type of first day you have. Fortunately for you, I happen to know of a few things you can do for yourself that will put you in the right mindset as you jump into your new job.
