What type of training would you need to advance in carpentry?

I know there will be people who will be surprised by my answers. Many years ago, a good carpenter was expected to train as an apprentice. Today, many people work at low-level jobs to get their experience. This is fine, but finding as much training as possible in how stuff works outside that first job will give you a great edge. For one, carpentry is essentially engineering. Learn engineering and you learn carpentry. Second, going to a trade school will expose you to folks who already have this knowledge, and there's a lot they know that's not common. It's silly to reinvent the wheel and make many mistakes if you can take advantage of what other smart people have already figured out. And then you build on that and discover new stuff which you can in turn share. Next (and I know folks will doubt this, but bear with me), get into computers. Why? You can't escape it. Plus, the next wave of manufacturing whether plastic or wood or metal will be in Rapid Prototyping. And there are some very, very cool tools coming out. If you're the person who has that "little edge" in the coming wave of hot technology, you'll be the "go-to guy or gal". The coolest carpentry tools in my garage are the ones with those "little silicon brains" embedded in them :-). Knowing this stuff gives you an entirely new insight on framing an extra room on your house.
