This paragraph in particular rankled me:
Perhaps your teachers exalted The Idea as the gem of creative work; taught you The Idea is the hard part. I disagree. Ideas aren’t to be trusted. They need to be wrung dry, ripped apart.
I want to inspire young/junior designers, not demoralise them, so I wrote my own, different, letter to a junior designer that’s based on my experience and published it alongside Cennydd’s original on A List Apart.
(This is my first article on A List Apart for eight years, eight years since Invasion of the Body Switchers. I won’t leave it so long next time.)
