Every hobby needs new blood. However I get fed up with trying to argue with a newbie over advise. When your coming up in the hobby, look to those that have been there before you, and follow them. When you have reached a plateau you can then start to debate your ideas. But you never will know crap about crap...
I have been doing my craft for 22 or 23 years now. It is the same in it. You take a guy/gal under your wing, he doesn't know squat, but thinks his the best thing that ever happened to the trade. He soaks up everything you teach him. Two years later he can work on his own, read some plans maybe even cobble his way through a job of his own with some help. Now he thinks he knows everything. Boy howdy he's the top dog now.He doesn't need you anymore. He can do it all. And for some time he thinks this way, stepping on the old timers all the way. Then one day he decides he needs to get a license to further certify his unmatched superiority in the trade. Well low and behold, he cant pass the test. He has no idea how to find these things in the code book, cause he cant even understand it (I mean he thinks who can....). Know he is hit with the reality. Not only does he not know everything, but in reality he doesn't know crap... If he passes his Journeyman's he will go through this cycle again. Except when he finishes taking his Masters 4 years later he will have learned, not only did I not know crap, but I never will know crap.....
I'll get off my box now...
