Emotional Intelligence (EQ) shows up in Customer Success where it hurts most: renewals under pressure, escalations, and exec conversations.
This is a short list of 5 books that build the skill fast, plus a simple CS cheat sheet so you can apply each one on real customer calls.
The 5-minute CS cheat sheet
Use this section even if you never read a full chapter.
When a renewal turns tense
First: lower threat (make it safe)
Then: name the real outcome you are protecting (time, risk, credibility, ROI)
When an escalation gets emotional
Validate emotion in one sentence
Move to facts and the next step in one sentence
Assign an owner and a timeline in writing
When you’re in front of execs
Read what matters: confidence, doubt, defensiveness
Keep the story tight: “Here’s what changed, here’s the risk, here’s what we’re doing, here’s what we need.”
One line you can use today (copy/paste):
“Before we solve, can I confirm what outcome you need protected right now?”
1. Emotional Intelligence: Why It Can Matter More Than IQ (Daniel Goleman)
This is the foundation. It explains why smart people still blow up relationships and how to stop emotional “hijacks” before they cost you trust.
Use this for (CS): high-stakes renewal calls, exec QBRs, internal alignment when teams are stressed.
Try this on your next call:
“I’m hearing frustration. Totally fair. Can we separate what happened from what we want next, so we can move fast?”
Key takeaways:
Self-awareness and self-control are skills, not personality traits
Emotions are signals; learn to read them early
Empathy is a business advantage when the stakes are high
2. What Everybody Is Saying (Joe Navarro, with Marvin Karlins)
Most churn risk shows up before anyone says, “We might leave.” This book helps you spot discomfort, hesitation, and resistance earlier through nonverbal cues.
Use this for (CS): discovery calls, stakeholder mapping, “something feels off” QBRs.
Try this on your next call:
“I might be reading the room wrong. What part of this plan feels risky to you?”
Key takeaways:
Observation beats assumptions
Look for clusters of signals, not one gesture
When you see discomfort, slow down and ask one clean question
3. The Untethered Soul: The Journey Beyond Yourself (Michael A. Singer)
CS is emotional labor. This book is about staying steady when your brain wants to spiral: blame, fear, defensiveness, urgency.
Use this for (CS): escalations, angry emails, internal politics, “this customer hates us” moments.
Try this on your next call:
Pause for 2 seconds before you respond.
Then say: “Got it. Let’s define the next step and the timeline.”
Key takeaways:
You are not your first reaction
Calm is a choice you can practice
The goal is better decisions, not perfect feelings
4. Emotional Intelligence 2.0 (Travis Bradberry & Jean Greaves)
If you want practical exercises, this is the one. It breaks EQ into four skills and gives simple ways to improve each.
Use this for (CS): building a weekly habit, coaching CSMs, and improving stakeholder communication.
Try this this week (10 minutes):
After every call, write one line under each:
What did they feel?
What did they want?
What did we commit to?
Key takeaways:
EQ = self-awareness, self-management, social awareness, relationship management
Small practice beats big intention
Track patterns, not one-off moments
5. Crucial Conversations: Tools for Talking When Stakes Are High (Kerry Patterson, Joseph Grenny, Ron McMillan, Al Switzler)
This is the “hard conversation” playbook. Perfect for renewal friction, pricing pressure, missed expectations, and exec tension.
Use this for (CS): renewal negotiations, scope resets, accountability, “we’re unhappy” calls.
Try this on your next call:
“What do you want for yourself, for your team, and for the partnership by the end of this quarter?”
Key takeaways:
Make it safe before you make your point
Separate facts from stories
Ask questions that reveal the real constraint
If you only read one
Start with Crucial Conversations if you deal with tense renewals. Start with Emotional Intelligence 2.0 if you want a weekly practice.
