Another quick one - sorry (bit hectic at the moment) but just thought I'd share this link to Fastcompany. They've just compiled this list of the best TED talks ever. If you're not into TED (Technology Entertainment Design) yet, then may I humbly suggest giving it a go? They get the very very best speakers all of the time to talk about a fascinating range of topics from sustainability to future mobile technology, human geography to the future of comedy. And best of all - it's all free!!
Anyway, here's the link to the best 10 talks ever - honestly, it's a bit of time you'll never regret spending. Go on....you know you want to.... http://www.fastcompany.com/magazine/148/greatest-hits-of-ted-videos.html
