And all the people -- and I think there's a lot of people at TED who do things because -- even though there's not an immediate return on the investment because it will only really pay off when everybody else has done it -- they'll do it because they're the sort of person who just does things which would be good if everybody else did them.
Ramai orang di TED  lakukan sesuatu walaupun ia tidak akan  datangkan kesan segera; ia hanya akan berkesan  apabila orang lain sudi lakukannya. Mereka lakukannya kerana  mereka ialah orang yang lakukan sesuatu yang akan datangkan kesan  jika orang lain juga lakukannya.
