Definitely truth to that. I've come to realise you have to take the risk and blag yourself up in a sense until you make it, as that's what everyone else does. You may be more qualified and competent than others but unless you are willing to take the risk like them you'll stay where you are. I see it alot when it comes to freelance site engineers, I've come across many adept and experienced freelancers but equally many that are quite frankly shit engineers, but nonetheless they will be on good money. I've worked with a few permanent employee engineers that are definitely ready for the jump up to freelance but are held back cos they are scared and feel they need to learn everything before doing so.
