Advice
It's more complicated than you think, at first... there are a lot of things to learn, remember, get used to, and keep straight, in order to feel fully at-ease with what you're doing, like you actually know what you're doing, and if an issue comes up you can take care of it. (:
Or, even so that if there is some new-to-you problem, you're experienced enough to quickly understand the job "lingo" when others help you by telling you how to remedy the problem. (like, "oh, yeah, okay" )
If you're not naturally outgoing that can take getting used to, too! But once you acclimate and feel at ease with doing everything, which just takes some time and practice, it's not bad at all. (:
