I’d say it may be a generational thing, but there seem to be people twice as old as me just coming in to the industry with similar confidence issues 
Personally I feel the lack of experience behind the wheel of a truck doesn’t help, there’s only so many hours people can afford for lessons and a test, and with all the insurance particulars and surveillance nowadays we can’t just easily tag along in a mate’s wagon for a shift and see how they drive it, plus all the [zb] that comes with a modern unit nowadays and their price tag, and the increasing number of impatient muppets in cars tearing around the roads like a race track, and wagon drivers getting the blame by default if there’s an accident involving a truck, it feels like there’s a lot at stake. Plus it feeling like most companies will just hand you the keys and say get on with it rather than spend a few hours on induction to show a newbie the ropes, like, I could have a guess at how to open and close a curtainsider but I’ve not been shown or taught it, and driving schools only cover what little is needed to pass the driving test and initial CPC 
But it has always been like this. I know that the old times like to hark on about being born on the engine hump of daddy’s Clydesdale 
, and learning to rope and sheet at the age of 5, but they are still in a majority. I would guess that at least for 4 or 5 decades, most drivers would have passed a test, and had to blag themselves into their first job. I’ve been driving here nearly 30 years, and it was a case of "no 2 years experience, no job " in the early 90’s, and no doubt before that in the 80’s.
I think it’s more to do with the social media obsession of naming and shaming, each and every mistake made, and people having become to ■■■■■■■ in receiving likes.
Just get behind the wheel, and get on with it. Honestly.
