As my husband is a carpenter, I would say Jesus learned from watching his father to be patient, to not lose sight of the goal while focusing on the teeniest of detail, to problem solve, plan, and adapt his hand to the condition of the wood to bring about the perfect end result. And last, but not least, to appreciate God's perfect design. (What I mean by that is carpenters get to appreciate the quality of the wood, and enjoy it's perfect form. They can even make a knot in the wood look glorious, when others would probably cut out the knot and throw it away.)
