Changing a manager’s behaviour isn’t just good leadership — it’s the fastest way to rescue a failing culture and unlock real profitability.

In this episode of The Independent Minds, host Michael Millward meets revenue strategist Debbie Longo, from Life in Bloom NY, to explore a deceptively simple idea: if you change the behaviour of managers, you can change the profitability of the entire organisation.

Debbie began her career in criminology before moving into commercial coaching, and she brings that sharp behavioural insight into the boardroom. She explains how negativity, ego, control, and manipulation quietly erode trust, damage team cohesion, and ultimately drive good employees away. As she puts it, even small moments of frustration can snowball into major organisational problems — “I drop a pen… the ink goes all over the floor…” — and unless leaders learn to interrupt these patterns, the business pays the price.

Michael and Debbie unpack why managers often cling to past successes, how ego distorts decision‑making, and why one person leaving can trigger a domino effect across a team. Debbie shares her practical method for breaking the cycle: a behavioural audit that helps leaders see their own actions clearly, often for the first time. She argues that sustained positivity isn’t naïve — it’s strategic — and that the most successful companies are those whose leaders continually examine and adjust their own behaviour.
