At 21 Tom Savage set up one of the world's leading non-profit conservation organisations, Blue Ventures, 24 hours from the nearest telephone in southwestern Madagascar.

Since then, he has founded a recruitment business with offices in London and San Francisco, won the Young Social Entrepreneur of the Year Award, the European Innovator of the Year award, featured in the Prime Minister's book Everyday Heroes and helped start Tenner, now supported by Sir Richard Branson. 

Inspired by Swiss Family Robinson, he also spent a year designing and building an eco-house in a remote part of Kenya and has travelled to over 60 countries, living in half a dozen. Closer to home, Tom now runs an award-winning big data business in Bristol, which he started whilst living in a van in Silicon Valley. 

For TEDxBristol he explores some of the head-scratching questions that he thinks many of us secretly ask ourselves every day about why we work so hard, and at what cost?
