What Coaches and Mentors Can Learn from Crossing the Chasm

Introducing a new approach to every mentee at once, using the same pitch that excited your most receptive mentee, is the specific trap Crossing the Chasm names, and it's an easy one to fall into when one enthusiastic response feels like proof it's ready for everyone.

03Deliver A Genuinely Complete Solution
04Expand Deliberately

This edition works through 4 core lessons — take them one at a time, not all at once.

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 mentee who embraced a new approach right away did so because they like trying new things, but another mentee might need to see it actually work before they'll fully engage.
Trying to introduce a new approach to all your mentees at once, before proving it with one, spreads your attention too thin to make it work well for anyone.
The more cautious mentee you need to bring along next won't engage based on enthusiasm alone; they need to see the complete, reliable version of how the approach actually helps.

The core lessons, applied to you

Understand That Different Audiences Adopt

Understand that different audiences adopt new things for different reasons

The idea

One mentee's enthusiastic embrace of a new approach doesn't mean another mentee will respond to the same pitch, since a more cautious mentee needs proof it actually works, not just excitement.

What it looks like

A mentor keeps pitching a new approach with the same enthusiasm that won over one receptive mentee, and a more cautious mentee remains hesitant because that pitch doesn't address their actual concerns.

Try this

Identify one part of your pitch for a new approach that relies on enthusiasm, and add a piece that instead shows proof it reliably helps.

Pick One Specific Segment

Pick one specific segment to win completely, rather than appealing broadly too soon

The idea

Fully proving a new approach with one mentee builds more credibility than introducing it to all your mentees before it's proven with anyone.

What it looks like

A mentor introduces a new coaching method to every mentee simultaneously, and uneven early results across mentees undermine confidence in the method before it's had a chance to prove itself with any of them.

Try this

Identify the one mentee where you could fully prove a new approach works, and focus there before expanding it to others.

Deliver A Genuinely Complete Solution

Deliver a genuinely complete solution, not just the exciting core idea

The idea

A more cautious mentee needs to see a genuinely complete, reliable version of a new approach, not just the exciting idea that won over the enthusiastic one.

What it looks like

A mentor introduces the exciting core concept of a new approach without addressing the practical support a more cautious mentee actually needs to feel comfortable trying it.

Try this

Identify what "complete" means for the mentee you're trying to bring along next, beyond the core idea, and address the biggest gap.

Expand Deliberately

Expand deliberately, one segment at a time

The idea

Once an approach has genuinely worked with one mentee, expanding it to others deliberately protects the credibility built with that first success.

When the clusters compete

Introducing today's approach to every mentee at once and fully proving it with one first aren't opposites — an approach proven with one mentee usually earns faster buy-in from the rest than an immediate rollout to everyone.

04 · Choose Your Priority

Name one thing, honestly

Is there a mentee you could fully win over to a new approach first, rather than introducing it to everyone at once?


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.
