" If possible, try to train yourself. Take home the instruction manuals or stay after hours and work on your own. Or arrange to be trained one-on-one, preferably by someone who puts you at ease. Ask to be shown a step, then to be left to practice it alone. Next, allow someone else to watch you who is not a supervisor, someone who doesn’t make you so nervous. "
