Starting work in one day

Starting work in one day. Working / Earning a living... It sounds unfamiliarly grown up~ Well, i shld have expected it from the time of graduation & job-hunting, but still. At this point of time, i question if i m ready. I think everyone does feel a bit uneasy before she starts work for a new job, esp the first job. Well, will my colleagues be nice? What scope or field are they expecting me to cover? How can i utilise my skills best? Thousands of questions flashing in my head~ Anxiety & eagerness to find out more~ Hope tomorrow will be fine. :)
