I had an old coffee can full of nails and an urge to teach my 7-year-old son how to properly use hand tools.
I passed him the hammer. Give it a couple starter taps, I told him, and then drive it in with one hard strike that is composed of clear mental focus, a strong grip and concentrated strength. It’s an acquired skill and you have to practice it.
By the time he worked over this firewood log it was like he had spent the summer working on a roofing crew.
