How it works

At certain points in your career, familiar strategies stop delivering the same results.

Work feels heavier.
Decisions take longer.
Confidence feels less steady.

This doesn’t mean you’ve become less capable.

It often means your decision pattern — and your response to pressure — needs reevaluating.

Often this happens before it becomes visible to others — but it affects performance.

This short diagnostic highlights how you’re currently leading — and the first stabilising shift to make.

Why The Diagnostic Works

This diagnostic is based on my work with senior leaders and executive teams navigating pressure, change, and increased responsibility

My aim is to quickly give you a clearer view of how you’re leading right now — and where a small adjustment may restore steadiness.

Designed by Gareth Mills — an award winning, globally certified strengths coach working with senior leaders, project and executive teams, certified in MBTI, CliftonStrengths, FIRO-B and TKI.
