How Celebrating Colleagues Fuels Career Growth, According to Tim Denning

In a recent LinkedIn post, Tim Denning explores the critical distinction between insecure employees who sabotage their peers and high performers who actively amplify them, arguing this difference profoundly shapes career trajectories.

Denning contrasts two management philosophies he experienced firsthand. The first manager, he recounts, was characterized by taking credit for his ideas and hindering his advancement. This manager, Denning states, “Kept me small so he’d look bigger.” In stark contrast, his second manager actively promoted his growth.

“Put my name on everything. Introduced me to his network. Pushed me into rooms I didn’t belong in yet.”

This second manager, Denning notes, has since become a CEO, while the first remains in middle management, illustrating his core thesis about the impact of professional philosophies.

The Scarcity vs. Abundance Mindset in Career Development

Denning identifies the “scarcity mindset” as a significant career impediment. This mindset is characterized by beliefs such as “If they win, I lose,” the perception of limited opportunities, and the feeling that others’ success diminishes one’s own. According to Tim Denning, this perspective inevitably leads to stagnation: “This thinking keeps you small. And alone. And stuck.”

Conversely, high performers operate from an abundance mindset, understanding that collective success benefits everyone. As Denning puts it, “Your colleague’s win is your win.” He elaborates on this by explaining that a colleague’s promotion enhances the reputation of those who developed them, a team’s project success elevates the entire team’s standing, and a departing colleague can become a valuable advocate in their new role.

The Power of Sharing and Amplification

Denning shares an anecdote about a VP who exemplified this principle. This leader actively forwarded opportunities that weren’t ideal for her, connected competitors with clients they could serve, and celebrated when her team members were recruited by other companies. “Every person I help up pulls me up with them,” she told Denning. This approach, he highlights, has led her to mentor over 50 executives who remain connected to her.

“Low performers hoard: Information, Credit, Connections, Opportunities, Recognition. High performers share everything. They know success isn’t finite.”

The compound effect of celebrating others, Denning argues, builds a strong network and reputation over time. He outlines a progression: from being a supportive colleague in Year 1 to a trusted connector in Year 2, a sought-after leader in Year 3, a network hub by Year 5, and ultimately, unstoppable by Year 10. Each celebrated win, he writes, creates an ally, whereas blocking others fosters animosity.

Identifying Future Leaders

Denning illustrates this point by recounting the downfall of a director who undermined his team by taking credit for their successes and blaming them for failures. Ultimately, his team members left to pursue leadership roles elsewhere, while he remained in his position. “Your team’s success is your success. Their failure is your failure to lead,” Denning emphasizes.

Ultimately, Denning encourages readers to shift their perspective on colleagues, viewing them not as competition but as potential future collaborators, advisors, or partners. “The person you help today might hire you tomorrow,” he concludes, prompting reflection on recent acts of support for peers.
