I discovered the secret to mastery by accident thanks to my girlfriends mum...
I was 18 and dating a girl I'd met in Manchester. Her mum asks what I do for a living.
At this time I was a university drop out building a tech company, and when she asked me I launched into this elaborate explanation about "leveraging social currency to build omnichannel media ecosystems that give students the power of community."
Her mum stares at me.
"So... you're building an online noticeboard?"
"Yeah."
That's when I knew I didn't understand my own business.
The truth is, if you can't explain what you do to someone's mum, dad or grandparents at dinner, you probably don't understand it yourself - and your customers definitely won't.
You're hiding behind jargon. Using complexity as camouflage for confusion.
Feynman knew this. The physicist who helped build the atomic bomb.
His test for understanding wasn't whether you could write equations. It was whether you could explain quantum mechanics to a child.
After that dinner with my girlfriends mum, I started doing something that changed my entire life.
I started pitching to people who were completely clueless about my industry - namely my friend Mike from university who worked in a call centre.
Before every client meeting, every pitch, every strategic decision, I'd explain it to Mike.
If he could understand it, then I knew I understood it.
I learnt that explaining forces understanding.
Teaching is where your ignorance gets exposed.
This is also incredibly effective in interviewing candidates for job roles.
So many people worked at a place that did something good and often claim credit for work they were not involved in.
So before I hire anyone, I ask them to explain their biggest achievement in their last role, like I'm a 10 year old.
The ones who can't? They're usually the ones who were passengers, not drivers.
My entire podcast is built on this. I ask the world's smartest people to explain complex things as simply as they possibly can - like I'm an idiot (helps that I often am).
The ones who actually understand their field make it feel obvious.
The ones who don't use bigger words and blame you for not keeping up.
Mastery isn't knowing all the complicated words - It's not needing them!
