What Coaches and Mentors Can Learn from On Writing Well

Renata was writing up session notes for a mentee before their next call, and the draft read that the mentee should "continue to operationalize their leadership development trajectory through intentional stakeholder engagement." She stopped and read it again, unsure what she was actually asking the mentee to do on Monday morning. The real advice, underneath the language, was much smaller: talk to your two skip-level reports before the reorg announcement, not after. She'd dressed the plain advice up because the fancier version felt more like something a professional coach should say, more like it justified the hour they'd spent together. But a mentee reading it before a stressful week needed the plain version, the one with an actual verb and an actual deadline. Renata rewrote the note in four sentences and sent it, feeling slightly less impressive and considerably more useful.

02 · Where Are You Now?

What's different for your conditions

Tap whichever ones sound like you. Nothing here is sent or saved — it's just for your own noticing.

The people you write for are often anxious or under pressure when they read your notes, so vague or padded language reads as unhelpful even when it's well-intentioned.
Coaching has its own specialized vocabulary — frameworks, models, stages — and using it fluently can feel like proof of expertise even when it's obscuring a simple, actionable point.
Your written follow-ups have to work without you in the room to explain them, unlike a live conversation where tone and follow-up questions can clarify a vague statement.
You're often synthesizing a long, meandering conversation into a short written summary, which means clarity of thought has to happen after the fact, under some time pressure.
The person you're writing for will likely act on what you write, so an unclear sentence has a direct, practical cost the next time they're in the situation.

Clutter Is The Enemy

Clutter is the enemy in your session notes and feedback

The idea
What it looks like

A coach writes a feedback email full of terms like "leverage your authentic leadership presence to drive stakeholder buy-in" because the vocabulary sounds like expert-level coaching language. The client reads it twice and still isn't sure what to actually do differently in tomorrow's meeting. Practice: After drafting any note, find the one sentence that contains the actual action you want the person to take, and move it to the top. Cut every framework term that isn't doing real work, and replace it with the plain verb underneath it.

Clarity Of Writing Requires Clarity

Clarity of writing requires clarity of thought about what the client actually needs

The idea
What it looks like

A coach writes that a client should "build greater self-awareness around communication patterns" without having pinned down which specific conversation or behavior prompted the note. The vague phrase covers for the fact that the coach hasn't yet identified the actual pattern worth naming. Practice: Before writing feedback, write down the one specific moment from the conversation that the advice is actually about. If you can't name the moment, the advice isn't specific enough to be useful yet, no matter how it's worded.

Revise Ruthlessly On The Summaries

Revise ruthlessly on the summaries clients rely on

The idea
What it looks like

A coach writes session notes immediately after a call, still full of the conversation's natural back-and-forth, and sends them unedited. The client receives a page of loosely connected thoughts instead of the two or three points that actually mattered. Practice: Write the notes, then cut them down to the three points a client would still remember a week later. If a sentence doesn't support one of those three points, delete it, even if it was an interesting part of the conversation.

Personality Survives Simplicity In Coaching

Personality survives simplicity in coaching feedback

The idea

A coach's actual judgment and care come through more clearly in a short, plain note than in one dressed up with framework language, because the plain version shows exactly what the coach noticed and thought mattered. Clients remember coaches who tell them something specific and true in a sentence they can act on, not the ones who sound most fluent in a model. Simplicity here isn't a loss of authority — it's frequently the clearest evidence of it.

When the clusters compete

Some clients expect and value the vocabulary of a specific coaching framework, so cutting it entirely can undercut the sense that a structured method is being applied. The workable approach is to name the framework term once, briefly, and then translate every actual instruction into plain, specific language the client can act on without decoding it first.

04 · Choose Your Priority

Name one thing, honestly

Look back at your last written note to a client or mentee — could they have told a colleague, in their own words, exactly what you asked them to do?


Good. Now look back at the "Try this" line under whichever lesson feels most connected to what you just wrote, and treat that as this week's actual assignment — not all 4 at once.

05 · Put It Into Practice
