The most powerful negotiation is the one you have with yourself. Because that’s the one shaping everything else.

I’m Glin Bayley, a writer and strategist helping leaders master the inner and outer game of negotiation.

MY PHILOSOPHY

Glin Bayley

Negotiation is never just about the deal on the table. It begins within you - how you make decisions, manage energy, and lead yourself.


And it extends outward - how you influence, collaborate, and create agreements that last.

My work blends both:

Inner Negotiation: self-leadership, alignment, and the identity work that fuels authentic ethical influence.

Outer Negotiation: the practical skills, strategies, and frameworks to create agreements that work.

Together, they create conscious negotiation, outcomes aligned with who you are, not just what you achieve.
