You write the way you speak, and readers aren't listeners.
Speech runs on fillers your mouth needs to keep pace with your mind; on the page they read as bloat, and bloated prose makes even a brilliant idea sound inarticulate.
William helped one client win a full-ride PhD and another a startup grant, all by compressing: cutting what the reader already has.
So does sounding articulate come down to what you delete?
Largely, yes — most of it is deletion.
Cut the empty tics, the doubled words, and everything one word already implies; then replace the wordy phrases that remain with a single exact word, and turn negatives into affirmatives so the reader stops doing arithmetic.
What's left is lean, and the reader hears the leanness as authority.
