Unfortunately that particular one month course is booked solid for the next twenty years so I guess I`ll never know for sure.
All the rest of the courses I`ve seen take at least a couple of months of intensive study to teach you the basics and then you have to follow up with a lifetime of refining what you really want to do before you can decide what you truly need to learn and who you need to learn it from.
Even if you finally arrive at that point where you have learned everything you need to know about a particular aspect of the craft, there`s no guarantee that you`ll still be moving in that same direction when you wake up the next morning.
Each new tree, new project, new tool and new technique bring an opportunity for additional learning experiences. Crank in a little metal, stone or other material besides wood into the mix and and you now have several lifetimes worth of learning to contend with.

Can I change my answer to no?
