Self-understanding as the foundation of effective leadership

Executive overview

Leaders who excel at strategy and execution often hit a ceiling when managing people. The gap isn't intelligence or technical skill — it's self-awareness and interpersonal capability. Margaret Andrews's MYLO framework (Motivation, Learning, Opportunity) gives leaders a structured path to grow on purpose.

You can't manage others well without first managing yourself. Understanding your own emotions, blind spots, and defaults is what enables you to understand — and develop — the people around you.

The best boss you ever had almost certainly led with interpersonal skills, not IQ.

Why self-awareness is hard to develop

• Looking inward surfaces things you'd rather not see — that discomfort causes avoidance.
• High achievers resist beginner status; admitting a soft-skill gap feels like losing ground.
• Success in early career rewards technical output, so interpersonal gaps go unpunished until they can't be ignored.
• Fear and anxiety masquerade as "everything is fine" until derailment is already underway.

The 85% finding

• Andrews runs a "best boss" exercise: participants list all the reasons why their best boss stood out, then sort into three buckets — IQ, hard/technical skills, interpersonal skills.
• Consistently, 85% of reasons land in the interpersonal bucket; IQ and technical skills split the remaining 15%.
• This doesn't mean intelligence is irrelevant — it means interpersonal skill is the differentiating factor between good and great.
• Great leaders help people "grow and glow"; that is remembered long after strategic wins are forgotten.

How leadership growth actually works

• Skill development follows an S-curve: slow improvement, then rapid gains, then a plateau.
• At the plateau, the question becomes: what is my next S-curve?
• Mistakes are necessary inputs — each error enables a more informed attempt next time.
• Interpersonal skills are learnable; being bad at them now means "not good at them yet," not "not capable."

Recognising derailment before it happens

• Career decline often mirrors Hemingway's bankruptcy: slowly, then all at once.
• High team turnover is an early indicator — where turnover is highest, poor management is usually present.
• Organisations tolerate interpersonal gaps in high performers until those gaps actively cause harm.
• By then, the damage — denied promotion, termination — has often already occurred.

Emotions as leadership data

• All emotions carry information; anger signals a crossed boundary, fear signals environmental threat.
• The diagnostic question: who knows you're angry first — you or the other person? If it's the other person, the relationship may already be damaged.
• Self-reflection after the fact builds pattern recognition for future situations.
• Pause before responding; asking "how do you think the meeting went?" pulls self-assessment out of the other person before offering your own view.

Managing up as a leadership skill

• Managing up means taking responsibility for the boss-subordinate relationship, not waiting for the boss to set its terms.
• Ask a new boss: how do you like to communicate? What do you want to hear from me, and how often? What will make you angry?
• Think of the boss as a partner: partners don't let each other fail; they share uncomfortable information proactively.
• Different bosses want different things — one may want advance warning on problems, another may just want them solved. Ask; don't assume.
• Managing up is not politics — it is relationship investment.

Navigating setbacks

• Ambitious leaders will have setbacks — attempting big or new things makes missteps inevitable.
• After a setback: accept what happened, identify your own contribution, then list what is and is not in your control.
• Focus exclusively on what is within your control.
• Setbacks can force a valuable reorientation — one example in the book: a failed business sale on the day Lehman Brothers collapsed led the founder toward ed-tech, now one of the largest in the world.

Sustaining growth over the long haul

• Leadership growth requires deliberate reflection time, not just more output.
• Andy Grove's reframe: if the board fired you and hired someone new, what would that person do first? Then do that.
• Avoid the sunk-cost trap of continuing in a direction simply because you built it.
• The market changes; what worked for 20 years may need a hard pivot before someone else exploits the gap.
