Life Lessons from Edward Packard’s “Nine Things I Learned in Ninety Years”

Overview:

• Quick, easy-to-read summary of the nine lessons Packard shares in his memoir.
• Language is simple so high school students can understand.
• Includes diagrams, a small interactive chart, math-style idea, and speaker notes.

This slide deck turns Packard’s nine life lessons into short, clear slides for classroom use. Use the speaker notes to expand on examples and guide discussion.

Roadmap of the Nine Lessons

What we will cover:

1. Be self-constituted.
2. Keep awake and aware.
3. Consider what others are thinking and feeling.
4. Make happiness your default.
5. Seek an eternal perspective.
6. Guard against self-deception.
7. How to confront mortality.
8. Recognize the outsized role of luck.
9. Notice and value what you have now.

Point quickly to each lesson so students know the structure. Mention that examples come from history, literature, and modern life.

1) Be self-constituted

Main idea: Build a stable, honest character and stick to it.

Why it matters: If you have clear values, you are less likely to be pushed around or make harmful choices.

Short example: Huckleberry Finn tries to do what feels right for everyone on the raft, showing kindness and fairness.

Talk about what “self-constituted” means: being guided by your chosen moral rules, not just impulses. Point out the risk: someone can be self-constituted but selfish, so the values must be kind and fair.

2) Keep awake and aware

Main idea: Don’t “sleepwalk” through life; pay attention to what you do and why you do it.

Why it matters: Important decisions made without awareness can cause big harm.

Real case: Leaders before World War I acted without truly understanding the risks, and that led to disaster.

Give a simple definition of “sleepwalking” as acting without thinking about causes and consequences. Encourage students to pause before big choices and check their reasons.

3) Consider what others may be thinking and feeling

Main idea: Use empathy and “theory of mind” to guess how others will react.

Why it matters: Thoughtless comments can hurt people or ruin chances to connect.

Short example: Packard once said a joke that offended an older man because he didn’t consider the man’s feelings.

Describe “theory of mind” as imagining someone else’s thoughts and feelings. Ask students to think of times a careless comment caused trouble and how it could be avoided.

4) Make happiness your default state of mind

Main idea: Be the kind of person who chooses compassion and respect every day so happiness becomes normal.

Why it matters: Small daily habits and attitudes shape long-term mood more than rare big events.

Quote idea: “More important than being loved is to love.”

Note

Try focusing on kindness each day; it often makes you and others happier.

Explain that the Dalai Lama suggests love and compassion lead to happiness regardless of religion. Mention practical habits: gratitude, helping others, and steady respect for people.

5) Seek an eternal perspective

Main idea: Try to see life from a broader viewpoint — beyond small, intense worries.

Why it matters: A wide view can bring calm and let you enjoy the present without being crushed by failure or desire.

Example: A monk who didn’t see failure in not spotting a snow leopard, but found the whole trip wonderful.

Stoicism

• Think about death to reduce fear.
• Practice self-control.

Spinoza-style

• Seek compassion without attachment.
• Find joy by understanding nature and life.

Use the column slide to compare two ways of gaining calm: Stoic training and broader, compassionate views. Ask students: Which fits you more, preparing for hard events or expanding what you care about?

6) Guard against self-deception

Main idea: Be careful that your feelings or wishes don’t trick you into believing false things.

Why it matters: Smart people can fool themselves by only noticing facts that match what they already believe.

Warning sign: If you only read or listen to people who agree with you, you may be trapped by confirmation bias.

Give a quick activity: ask students to list one belief they feel sure about and then find one strong argument against it. Explain that checking yourself helps better decisions and relationships.

7) How to confront mortality

Main idea: Thinking about death calmly helps you live better and be less afraid.

Why it matters: When you accept that life ends, you can focus on what matters now and act kindly.

Examples: Montaigne and Katherine Hepburn were calm about dying and focused on simple pleasures like gardening.

Emphasize that the goal is not morbid worry but a healthy acceptance that encourages meaning. Suggest small practices: imagine what you’d want remembered about you, or write a short letter to family.

8) What an outsized role is played by luck

Main idea: Many things about our lives come from luck — birth, chance opportunities, and random events.

Why it matters: If luck matters, we should be more humble when we succeed and more kind to people who struggle.

Modern example: Some rich people became wealthy by luck and then influence rules to stay rich.

Point out that recognizing luck encourages generosity and compassion. Ask students to name one thing in their lives they think was due to luck.

9) Consider what you have at the moment

Main idea: Notice and appreciate what you own and who you are with right now.

Why it matters: People often only notice good things after they’re gone.

Shakespeare line: We prize not what we have while we enjoy it, but when it’s lost we find its true value.

Encourage a short classroom exercise: have students write down three things they often take for granted. Discuss how gratitude practices can improve mood and relationships.

Quick “math” idea about Luck and Effort

\[ \text{Outcome} = \text{Skill} + \text{Effort} + \text{Luck} \]

Interpretation: Work hard and get better skills, but remember luck still helps a lot. Use this to stay humble and to help others when you can.

Explain the equation as a simple way to think about success. Stress that it doesn’t remove the value of effort, but it adds perspective.

Interactive chart: Emphasis on each lesson

This bar chart shows a simple score for how strongly each lesson is emphasized in the book. Invite students to suggest different scores and explain why.

Short classroom activities

• Pair-share a time you “sleepwalked” and what you’d change now.

• List one habit to build kindness and one way to check your own bias.

• Write a 1-minute gratitude note for something you usually take for granted.

These activities are quick and help students practice the lessons. Use them to spark discussion or reflective writing.

Final Takeaways

• Build a steady character and stick to kind values.
• Stay awake, imagine other minds, and be compassionate.
• Make happiness a habit, accept death calmly, and know luck matters.
• Notice what you have now and be thankful.

Note

Small daily choices add up more than big dramatic ones.

Wrap up by encouraging students to pick one lesson to try for a week. Tell them to notice any changes in their mood or relationships.
