Get physically fit if you are not now.
Break in your work shoes before you begin work.
Plan how you will feed yourself on work days. Cafeteria? Bring in food? Crock-pot for dinner after work? Fast food?
Have one or two alternate routes for the trip to work.
Plan back-up childcare and emergency back-up childcare if needed.
Don't get too excited, not to burst ur bubble. But they glorified the crap out of nursing when I was in school. Some of my classmate and myself were a bit disillusioned with what it was going to really be like. Never been so overwhelmed and tired after 12 hrs in my life, oh and not to mention totally unconfident about anything, I felt like everything i learned was wrong and I knew nothing. Wellll after 8 months I work in an ICU/CCU on my own, so it does get better.....eventually.
