Diligence and attention soon gave him the knack of it, and he strode down the street with his mouth full of harmony and his soul full of gratitude. He felt much as an astronomer feels who has discovered a new planet–no doubt, as far as strong, deep, unalloyed pleasure is concerned, the advantage was with the boy, not the astronomer.

As read from The Adventures of Tom Sawyer.

The “knack” is typically a trait linked with natural ability, not diligence and attention.

In the movie “Hunt for the Wilderpeople” Ricky Baker and his foster uncle, Hec get lost in the New Zealand bush. They split up to find food. The boy, raised in the city can’t catch a thing worth eating. Hec, played by Sam Neill catches a catfish with ease.

They eat.

They sit by the fire.

Ricky Baker asks Hec: “How did you catch that fish?” Hec replies. “I don’t know, I have the knack.” (all paraphrased.)

Don’t dismiss the “knack”.

Don’t dismiss diligence and attention.
