Host: Justin Colby

Date: March 25, 2026

Episode Overview

In this episode, Justin Colby sits down with Glenn Sharp, founder of Sharp Leadership Development and the author of "Now What?" With more than 20,000 managers trained, Glenn brings a wealth of real-world experience on building leadership efficiency, mastering time management, and the often-overlooked difference between management and leadership. The discussion dives deep into what makes a good leader great, the challenges entrepreneurs face as business grows, the necessity of training and delegation, and the lasting impact of investing in people.

Key Discussion Points & Insights

The Importance of Upfront Investment in People

Timestamp: 02:36 – 04:17

• Glenn Sharp's "Green Line vs. Red Line": Glenn explains the critical concept from his book about proactively investing in expectations and training, comparing approaches:
  • Not investing up front leads to mistakes, inefficiencies, and frustration.
  • Clear expectations, thorough onboarding, and early training save exponential time and headaches downstream.
• Mentorship: Assigning new hires a "big brother or big sister" improves acclimation and confidence.

Notable Quote:

"Those who put the most work in up front… literally don’t experience half the things that people who are reactive and just wait for things to happen experience."
— Glenn Sharp [03:28]

Delegation & Opportunity Cost: Why Leaders Get Stuck

Timestamp: 05:54 – 09:20

• Delegation is the Achilles heel for most entrepreneurs and managers.
  • Most common reason leaders don’t delegate: "I don’t know why."
  • Underlying issues: control, trust, fear of being expendable.
• Opportunity cost—borrowed from finance, but vital in leadership. What could a leader be doing if freed from routine tasks?
• Practical Example: Glenn’s advice to his son in a snowbound business: "Train employees on specialized tasks during idle time instead of sending them home. The ROI on teaching skill sets is immense."

Notable Quote:

"Your time is more valuable than the people that work for you. I did not say you are more valuable... but your time is!"
— Glenn Sharp [34:01]

Why People Leave Jobs: The Untold Truths

Timestamp: 09:26 – 12:16

• The classic myth is that people leave for more money; data shows manager relationships are #1, money only as high as #5.
• Career path and personal development is rising as the second biggest factor for retention—especially in Gen Z.
  • Gen Z values direct training and marketable skills over promises of promotion.

Notable Quote:

"Gen Zs want training… They will even sacrifice money in some cases in order to be trained because very few organizations actually train them."
— Glenn Sharp [11:34]

The Player-Coach Divide: Why Top Performers Aren't Always Top Leaders

Timestamp: 12:43 – 15:36

• Being an expert contributor does not mean being a good manager.
• Over-promoting top sales or technical performers often fails unless they’re trained for leadership.
• Reference to sports: Michael Jordan’s greatness as a player didn’t translate into patience or skills necessary for coaching.

Notable Quote:

"Just because you're a really great trainer does not mean you'd be a good manager of trainers. It's a completely different skillset."
— Glenn Sharp [13:21]

Management vs. Leadership: The Crucial Distinction

Timestamp: 21:43 – 25:07

• Managers: Focused on tasks, outputs, numbers, and administration.
• Leaders: Possess vision, influence, and the ability to lead teams through the "valley of despair" during change.
• Successful leaders:
  • Prepare the team for challenges and setbacks.
  • Involve staff in planning and communicating expectations.
  • Understand "it has to get worse before it gets better."
• "Vision and influence" are the essential qualities that separate leaders from managers.

Notable Quote:

"A leader will understand that it's going to get worse before it gets better… They don’t overreact when things get hard... they put the effort in up front."
— Glenn Sharp [22:57]

Change Management: Listen to the End User

Timestamp: 25:11 – 31:49

• One of Glenn’s mantras: Never implement change without consulting the end user.
• End users (or front-line workers) are the richest source of operational insight.
• Real-life case: A costly failed deployment in an aviation company could have been avoided with a ten-minute call to staff on-site.

Notable Quotes:

"Why would you ever make a change without talking to the end user?"
— Glenn Sharp [25:11]

"Not only do you get great ideas from them, but you show them respect by listening to them. It’s incredible how many people miss that."
— Glenn Sharp [25:33]

Time Management for Entrepreneurs: Work Smart, Not Just Hard

Timestamp: 31:49 – 40:36

• Glenn’s practical system for time management:
  • Identify high-value tasks only the leader should do.
  • Systematically train others for lower-level tasks, even if it means investing more time up front.
  • Don’t let ego or perfectionism prevent delegation.
  • Hire and empower people better than yourself at specific functions.
• A Miami case study: Dedicating two weeks to training saved a manager 5–6 hours every week thereafter; compounding efficiency with each person trained.

Notable Exchange:

Justin: "You’re sacrificing 30 minutes a day for two weeks, for quite literally five hours a week, forever."
Glenn: "And it’s the gift that keeps on giving, right? That is investing your time versus spending your time."
[38:29–38:38]

The Role of AI in Leadership and Management

Timestamp: 41:17 – 44:26

• Glenn is optimistic about AI as a tool but cautions:
  • Real connection and influence remain human skills.
  • Overreliance on technological shortcuts (like email or training modules) weaken team culture and communication.
  • Gen Z and younger workers know digital communication is not enough; they crave real interpersonal skills and authentic leadership.

Notable Quote:

"Please remember the key to business is connection. It always will be, it always has been and always will be connecting with people… So AI will be a great tool. But don’t try to substitute AI for that connection."
— Glenn Sharp [41:32]
