I was very lucky that, when I worked for Oxfam and other big charities, I could read lots of big reports on what influenced politicians and businesses and the general public, what campaigns worked really well, which ones didn't.
Tive a sorte de, ao trabalhar para Oxfam e outras instituições grandes, poder ler montes de relatórios sobre o que influenciava a política, os negócios e o público em geral, quais campanhas davam certo, e quais não davam.
