Ch6. The Attitude of Positivity — What Carnegie Learned from Lincoln

Overview: The Foundation Beneath It All

Relationship skills, overcoming worry, speaking — all rest on one thing: attitude. Two people may know the same principles, yet one’s life changes and the other’s doesn’t. The difference is attitude and enthusiasm. This final lesson distills the mindset at the foundation of Carnegie’s thought, through the life of the man he deeply admired — Lincoln.

Goal of this lesson: Understand the positive attitude of enthusiasm, habit, tolerance, and patience, and apply the core of Carnegie’s self-management to life.

1. Enthusiasm — Turning the Ordinary Into the Extraordinary

“An ordinary person with enthusiasm beats a genius without it.”

Carnegie put enthusiasm ahead of talent. Curiously, he said “act enthusiastic and you’ll become enthusiastic.” Emotion shapes action, but action also shapes emotion.

When you lack drive, don’t wait for drive to arrive. Act energetically first, and the feeling follows. Smile and you grow cheerful; square your shoulders and confidence rises. Attitude can begin with the body before the mind.

2. Habit — The Bridge That Turns Principles Into Life

Knowledge is power only when applied (Lesson 1). And repeated application becomes habit. Carnegie’s principles change a life not through one resolution but when engraved into the body through small daily practice.

Focus on practicing one principle at a time
When it goes badly, don’t blame yourself — try again
Record and acknowledge small successes (the appreciation of Lesson 2 applies to yourself too)

3. The Attitude Learned from Lincoln

Carnegie studied Lincoln deeply enough to write Lincoln the Unknown. What he saw in Lincoln wasn’t great achievements but attitude.

Lincoln’s attitude	Meaning
Tolerance	”With malice toward none, with charity for all”
Not criticizing	After nearly facing a duel over a stinging critique in his youth, he never again condemned people lightly
Patience	He never stopped amid repeated failures and defeats
Empathy	He tried to grasp even an enemy’s point of view

When angry, Lincoln would write a letter — and not send it. The wisdom of venting anger without wrecking a relationship. The reason Carnegie loved the principle “don’t criticize” (Lesson 2) is here — it was a truth Lincoln proved over a lifetime.

4. Carnegie’s Legacy — Beyond the Critics

Some dismiss Carnegie as “shallow people-pleasing.” But his core is not manipulation but the modern translation of an old ethic: genuinely respect others. Take only the technique and remove the sincerity, and it won’t last — remember this, and Carnegie remains a valid teacher.

His principles all gather into one Golden Rule — “Do unto others as you would have them do unto you.”

5. Closing the Series — The Four Pillars in One Line Each

Relationships: from self-centered to other-centered
Worry: shut out yesterday and tomorrow, live today
Speaking: prepare, narrow the core, deliver with sincerity
Attitude: enthusiasm from action, a life changed by habit

All of Carnegie’s teaching converges on sincerity toward people and the attitude of living today. Now practice it in daily life, one principle at a time.

Principles change a life when they become repeated practice — habit.
Lincoln’s tolerance, patience, and empathy are a living model of Carnegie’s thought.
Carnegie’s essence is not people-pleasing but sincere respect for others.
The four pillars (relationships, worry, speaking, attitude) converge on sincerity and living today.
