The Ethical Will: Why Character Requires Intentional Design

The biggest obstacle to effective leadership and parenting is not a lack of information, but the lack of a clear plan for building character. Society focuses on measuring performance through grades, promotions, and bank accounts, while leaving the foundation of character to chance. This conversation with Lt. Gen. Mark Hertling shows that character is not an innate trait that appears on its own. It is a system that must be engineered, reviewed, and passed down. When we fail to explain our own mistakes to the next generation, we force them to repeat our failures through trial and error. For leaders and parents, the real advantage comes from moving from ghosts who haunt our descendants with unexamined patterns to ancestors who provide a map for navigating the challenges ahead.

The Architecture of Character

In most professional and personal settings, we treat character as a bonus that comes with success rather than the main ingredient. Hertling argues that this is a design flaw. We spend our time chasing metrics, such as money or status, while assuming that if we are generally good people, our character will take care of itself.

The truth, as Hertling notes, is that character requires as much focus and effort as any high-stakes business or military operation.

"I don't think we talk as much about the precision of developing character as we should. You know, we assume it will happen if they're good people, but boy that's part of the reflection too of what are your values? What are your behavioral patterns? What do you talk about at dinner and the things that build who you are to be that good person? That takes as much effort as being a great business person or lawyer, minister, or whatever."

When we do not define our values, we default to measuring our lives by external rewards. This creates a loop where we prioritize the wrong things, leading to high-performing individuals who lack the internal compass needed to handle ethical complexity.

The Competitive Advantage of Scar Tissue

Conventional wisdom says we should show a polished, successful version of ourselves to our children and subordinates to inspire them. Hertling suggests the opposite: the most valuable legacy is an honest account of failure.

By sharing his scar tissue, Hertling helps the next generation recognize patterns more quickly. When we hide our mistakes, we force those who follow us to walk into the same traps. Shame acts as a barrier that stops the transfer of hard-won wisdom.

"Most leadership books are people saying how great they were and how they succeeded in everything. He says, you have more scar tissue than you have successes in this book. And that's the first time I've heard anybody say that. And I said, yeah. And it was kind of picking the scabs as I went through to give advice to our sons don't do what I'm doing here."

When we treat our lives as an ethical will, we pass down values and lessons rather than just material assets. We stop being a ghost that haunts the family with unresolved patterns and become an ancestor who provides a clear map of the terrain.

Systems Thinking: Reviewing the Self

The Stoic practice of reviewing your own behavior is a way to debug how you act. Without this daily audit, we operate on outdated habits. Hertling emphasizes that we cannot expect our children or our teams to develop this skill if we do not model it ourselves.

The system responds to what we measure. If we only talk about outcomes, we get performance. If we talk about the process of decision-making and the values behind our choices, we build character. The payoff is significant: by being honest about our own struggles, we reduce the cost of trial and error for those who follow us. We do not spare them from making mistakes, but we spare them from making the same mistakes, allowing them to start from a higher level of maturity.

Key Action Items

• Establish an Ethical Will (Immediate): Start documenting your core values and the reasons behind your major life decisions. This is not for your estate, but for the character development of those you lead or raise.
• Audit Your Dinner Table Conversations (Immediate): Over the next month, track how much time you spend discussing external performance versus internal character. Shift the focus toward the latter.
• Normalize Scar Tissue (Ongoing): When you fail, explain the specific decision-making error to your children or team. This creates a culture where learning from failure is the standard, rather than hiding it.
• Implement the Daily Review (1-2 weeks): Adopt the Stoic practice of reviewing your day at night. Ask: What did I do well? What could I have done better? Use this to recalibrate your compass for the next day.
• Build the Ancestor Mindset (12-18 months): Evaluate your current habits and family secrets. Ask yourself: Am I passing this pattern on as a ghost, or am I breaking it to become an ancestor? Identify one generational pattern you intend to stop this year.
