I'm old enough that I took drafting in 7th grade. One tip I remember is to turn the pencil slightly as you use it. I think this was to help maintain the pencil's shape, but there my be other less obvious reasons.

I took woodshop too. The shop teacher seemed to enjoy scaring us with stories of the students that goofed off in shop to horrific consequences. That's also where I learned to be careful with air compressors around open wounds.

That sounds like you may have learned the same way I learned that 1: when a USGS topo map indicates an unimproved road, it may be out of date, 2: don't take your father's four-wheel-drive truck down a late-winter, corn-snow-covered dirt road when the temperature is starting to drop in the late afternoon 3: Don't go down a dirt road on a hill covered in corn snow without walking the path first to make sure you can get out or get back up. 4: When looking for a winter campsite for your Boy Scout troop, tell your parents where you're going.
