When you start to look for what you have done wrong, you will eventually also start to think about how you might go about the work so as to minimse the chances of that mistake happening again. Once you start doing this you have entered the world of technique. This word encompass the way you choose, use and prepare tools and wood, which work methods you adopt, how you organise your workspace, and even the fathomless world of mental attitude.

Beautifully written piece.
