I thought I was good at writing because I got A’s in English class

Turns out writing academically and writing to resonate with others are two completely different kinds of writing.

Kind of like apples and oranges.

Or pie and cake.

Or a pond from a river.

Here’s the difference. 

Succeeding in academic writing means your teacher liked your work. 

Succeeding in copywriting means the market resonated with what you said. 

A grade cannot tell you whether or not you’ll be successful at the latter.
