I´ve been catching up on some TED Talks I regularly download and these are absolute no-miss:
Jamie Oliver´s take on obesity as a major public health problem and the fight against it;
Jaime Lerner´s insights on city design, mobility and sustainability, definitely a lesson worth receiving;
Stefan Sagmeister explaining the power of taking time off (I liked the example of Porto´s Casa da Música visual identity project, very interesting way of going beyond what is normal in graphic design);
and the surprising talk given by Dan Pink on the science of motivation.
They´re so inspiring that I think I really need to take a nap to absorb it all. (It´s too hot to work anyway.)
