I just started a job about 6 weeks ago. I'm still doing new things to this day (they just put me on registers for the first time since training yesterday... scary!). I'm definitely anxious that I'll mess up (and I have, I forgot to clock out yesterday, oops!), but I have a good supportive leadership team that for the most part knows how to talk to me to get the best results. For example, I don't take criticism well, it tears me up and eats away at me, but positive reinforcement works wonders with me and now that they know that they use it. I am naturally shy/introverted, to an extreme, so I have to push myself out of that comfort zone constantly and put on a perky, outgoing personality. It's tiring, I'm wiped by the end of even a 4 hour shift, but my enjoyment in what I do gets me through it, even the 8 hour shifts. And when I start thinking too many negative thoughts I remind myself this is the first step on my career path and I just need to get through this for 6 more months before I take my next step. And then I'll start new again with all the same fears and anxiety!

Just remember, they'll teach you everything in training that you need to know, and there's no such thing as a stupid question. It's better to ask something that would seem obvious to others than not to and get it wrong.
