Quit playing nice.

I didn’t grow up confident, fearless or ‘high-performing’. I was anxious, desperate to be liked, riddled with imposter syndrome, and hated speaking in groups. I was known as the ‘nice’ boy.

So whilst I spent decades running away from conflict, it’s a full circle moment where I now teach it to leaders and teams.
