If you can’t explain your idea to a five year old, you don’t understand it as well as you could.
Some say that those who can’t do, teach – and this might be true of some poor teachers.
What seems more likely to me is that those who can’t teach, can’t really do.
Perhaps they can perform in a vacuum, or regurgitate quotes and information they’ve been incentivised to memorise. But when it comes to passing the baton, they flounder.
True masters tend to be excellent teachers.
Because excellent teachers tend to be excellent students.
If follows that when playing any infinite game the teachers and the students come out on top.
Make a habit of breaking down the things you do and the things you think know into the tiniest details.
Fail to do so, and you might find yourself trapped in a cage of ideas too grand for your even your own comprehension. A sad place to be.
Become fluent in the language of that detail, and you’ll be able to share what you know with anyone.
