getting accustomed to work is the least of your problems..staying motivated is what you have to do...build work ethics.. like not being late,not calling in sick when your not sick,standing around watching fellow employees work around you..keep doing something,..ask what needs to be done..look around..maybe the trash cans need to be changed...there's a whole lot to be done...keep yourself motivated n good luck !
it is all up to you and the attitude you chose. Everyone is nervous at interviews and everyone is a bit scared when they start a new job. You will flub somewhere, just move past it and stay positive. It will only be as hard as you make it. Don't over think and don't stay focused on the goofs. Focus on the learning.
