My dad had played in an informal team, Dumpster Diving, a few times and I had only seen him get it wrong. A pretty impressive feat, since he was utterly fearless about diving on his hands and knees.

Anyway, there was something I wanted to show him about myself as a proud Dumpster Diving Australian while imagining what it would be like if he’d actually got it right—right up to the Dumpster he dove into—because I was really proud of my own diving skills, whereas he just wasn’t. I wanted to show him how it feels to learn something by doing it yourself, by explaining it to someone, so that it’s as impactful as what he was trying to do himself. After all, anyone could learn how to save someone’s life by doing something they think about every day and imagining that their life might be saved by seeing themselves do it—or someone else doing it.

Getting to the point where I wanted to dive into my dad’s team’s botched scheme and say, “Excuse me, which part is which?” was something I spent some time getting to, via my first-person perspective in the YouTube video, which became an incredibly valuable teaching tool for me. I’m not sure I could have spent three minutes with him if I hadn’t done the video. It taught me the more general concepts around how to learn difficult things, and how to do it all in a casual, non-dangerous way.
