>People want to come across as valuable to others and one way we do that is by offerring expertise.
I've found the trick to getting over this is realizing no matter how good you are at something, there's always someone better and when you find yourself as the noob, you get to ask all the questions and learn and everbody will be ok with this. You also get to make mistakes, and everybody will be ok with this.
I've recently found myself going from being the expert to bottom of the barrel noob again and honestly it's refreshing, there's no pressure on you, somebody else makes the decisions, you just kinda do what you're told and absorb knowledge, and when something goes wrong you don't need to figure it out. It does make a nice change, though it can be frustrating, especially when it's a situation when you know what to do, but nobody listens because you're the noob.
You just have to remember, at some point you won't be the noob again and someone else will be, might as well enjoy it while you can.
It's also kind of an interesting situation, I started my new job just after a younger guy who's only had one or two other jobs before. There's a big difference between the way the two of us learn and work just because of our gap in life experience. It made me realize there's different levels between even noobs based on a bunch of different factors.
In the end though, i've found it best when you're the noob to just learn whatever you can as fast as you can, bring whatever knowledge and experience you can, but do it unspokenly through actions rather than words and eventually, without realizing it, you're not the noob any more.
