Adventurer Sally Kettle argues that hope is not helpful, and suggests some alternative strategies.

Sally has twice rowed the Atlantic Ocean, and worries that hope can lead to a passive state of mind. There is nothing, she believes, like taking concrete steps to make things happen.

Four Thought is a series of talks which combine thought provoking ideas and engaging storytelling. Recorded live in front of an audience, speakers air their latest thinking on the trends, ideas, interests and passions that affect our culture and society.
