You seem to me a level headed guy, that's taking in what your learning. You make a lot more sense, than some of the newly qualified sparks on the forum. You also tend to only ask about those tricky type questions, not the stuff that should have been well and truly learnt and become second nature!! ..lol!!
Now if a lot of that is down to the Boss/Electrician your working for, then my hat's off to him, he's doing a decent job of training one of the better future sparks into our industry.
When you have gained enough experience in the workplace, start thinking outside the box, look around and find a specialisation. One that is interesting and will be lucrative for many years to come. As an example, ...a high end testing commissioning Tech/Eng Covering everything from your usual 17th ed stuff, setting up VCB, GCB etc, protection relays and control, to protection co-ordination studies. It will involve learning and using both primary and secondary injection test kits, and a hell of a lot of other test kit, that you have probably never even heard of yet!! That profession has the ability for you to see the world, while being highly paid in the process. ...lol!!!
Wish you luck anyway, in whatever field you choose to follow or specialise in....
