Giving Tuesday was launched in 2012 on the Tuesday after American Thanksgiving, as an annual celebration of generosity in all its forms. It has grown rapidly into a global grass roots movement, drawing together people around the world who share a love of serving their fellow humans with their time, expertise and money. Asha Curran has been involved in Giving Tuesday from the start, helping her then boss, Henry Timms, launch the idea. Now she is the CEO. For Driving Change, Matthew Bishop – another member of the launch team – asked Asha to reflect on what lessons have been learned over the past 8 years, including about how to engage people in working for a better world.
