Plant just a few trees. Don't be afraid to reject your own ideas. Humble brag in a journal.
This is some of the advice we heard last week when about 1,500 people who try to make our planet a better place – from scientists and philanthropists to activists and entrepreneurs – descended on Oxford, England. In big forums and little coffee shops, they discussed what to do about some of the world's biggest problems and swapped advice from their work on the front lines. The Skoll World Forum brought these people together in a bid to "accelerate innovative solutions."
