Those Who Can Do, Also Teach

The idiom “those who can’t do, teach” originated from George Bernard Shaw in his play Man and Superman. It was originally intended as a cynical jab at political revolutionaries rather than an attack on educators. Over time, it morphed into a popular, often derogatory, stereotype suggesting that teachers are simply people who failed at their primary vocational goals. Which is so not true.

Interestingly enough, the original maxim goes all the way back to Aristotle which reads, “Those who know, do. Those who understand, teach.” In other words: Only those who truly understand complex ideas can break them down for others to understand.

Wanna know if you really grasp the fundamentals? Wanna get better at your craft?

Try teaching it. There’s no better test than that.
