Episode: 3302: “The Number One Impact on Your Investments is YOU” by Kent Thune with Get Rich Slowly
Original Air Date: October 1, 2025

Episode Overview

This episode, hosted by Diania Merriam, centers on the profound yet often overlooked truth in personal finance: the biggest influence on your investment success is not the market, the economy, or government policy—but you, the investor. Drawing from a guest post by Kent Thune via Get Rich Slowly, the show delves into the importance of self-understanding, self-control, and the need to shift attention from uncontrollable external events to the factors you can control in your financial journey.

Key Discussion Points and Insights

Market Volatility & Fear: Where Do We Turn?

• Context: Recent market volatility and economic fragility have shaken many investors' confidence.

• Insight: Standard questions in times of uncertainty—“What if the market crashes?”, “Should I adjust my investments?”—are inherently reactive and focus on the external. Instead, the episode urges listeners to ask deeper, more personal questions about their own goals and paths.

  “Those kinds of questions suggest we’ve not sought answers from internal sources and perhaps have failed to ask questions that may be a bit more difficult, such as 'Who am I? And where am I going?'” (Kent Thune, 02:08)

What You Can’t Control

1. Financial Markets

• Markets are unpredictable: Echoed in the famous Keynes quote:

  “The markets can remain irrational longer than you can remain solvent.” (02:23)

2. The Economy

• Cycles are inevitable, but history doesn’t precisely repeat:

  “History may rhyme, but it does not repeat itself.” (02:43)

3. Government Actions

• Tax rates, interest rates, or geopolitical moves: All are impactful, none are in your hands.

What Is Within Your Control

1. Asset Allocation

• Diversification decisions and choosing the type of investments (mutual funds, index funds, etc.) are up to you.

2. Time in the Market

• Emphasizes long-term investing over market timing:

  “Miss the market’s greatest moves and you’re doomed to underperformance.” (03:55)

3. Savings Rate

• Maximizing how much you save/invest will have a larger cumulative effect than market performance:

  “Increasing the amount you’re saving or investing will have a much larger impact on your long-term account value than market movements or economic activity.” (04:13)

4. Your Personal Goals and Risk Tolerance

• Get clear on your reasons and time horizons before crafting an investment plan.

The Power of Self-Reflection: Practical Guidance

1. Find Yourself

• Self-awareness is step one—for personal finance and for life.
• Recommended resources:
  • Emotional Intelligence by Daniel Goleman (for understanding yourself as a human)
  • Online Myers-Briggs Type Indicator (for understanding your individuality)

2. Define Yourself

• Don’t just accept society’s definitions. Define terms like "retirement," "wealth," "success," and "freedom" for yourself.

3. Allocate Attention

• Be intentional with information consumption.

  “If we’re consumers of information, we must stop to think of what it is that information consumes—our attention.” (Kent Thune, 06:19)

• Create a media “portfolio” to avoid drowning in market noise.

4. Think About Thinking

• Metacognition (reflecting on your thought patterns) strengthens judgment.
• Suggested reading: The Complete Idiot’s Guide to Philosophy for accessible philosophy insights.

Notable Quotes & Memorable Moments

• On Control:
  ​> "Allocate attention to things we can control and ultimately to set forth on our own path rather than the path of others.” (Kent Thune, 02:04)

• Lao Tzu Reference:

  “If I’ve even just a little sense, I’ll walk on the main road and my only fear will be straying from it.” (Kent Thune, quoting Lao Tzu, 05:08)

• On Growth & Mistakes:

  "We will make mistakes, of course, but they will be our own. And because of our self-awareness, they’ll help us to grow stronger and to continue in the right direction." (Kent Thune, 07:21)

Host Commentary & Supplemental Reflections

Diania Merriam brings personal perspective to Kent Thune’s advice:

• Investing is Easy; Saving is Harder:

  “Investing is the really easy part when it comes to money. The much harder part is money management and actually having enough of a gap between your income and expenses to put towards investments.” (Diania Merriam, 10:27)

• Embrace Volatility:

  “We need to expect volatility. The stock market is a roller coaster. That’s just how it works. But if we’re in it for the long haul and we’re properly diversified, we’re going to be fine.” (Diania Merriam, 10:41)

• On Index Funds & Savings Rate:

  “I could probably drive myself crazy diving into investment strategies that get the absolute best return, but matching the overall market return through index fund investing is going to get me to my financial goals... Think of it this way. If person A saves $100 with a 50% return and person B saves $150 with a 10% return, who’s better off? Person B.” (Diania Merriam, 11:01)

Conclusion
