Gamechangers

In his new book, Tom de Bruyne shows that real change doesn't begin with grand words, but with smart, small interventions. One push on the right cog can make a system creak – and sometimes even break it wide open.

"How small interventions unleash big change by Tom de Bruyne is at once a love letter to the courage of changemakers and a razor-sharp manual for anyone navigating the minefield of societal transition. This is systems thinking at its smartest and most narrative. And the vivid examples make it a book you won't want to put down."

Claire Thielens, Nederlandse Vereniging Duurzame Energie (Dutch Association for Renewable Energy)
