TED Talks are brilliant 18 minute sessions where the speaker delivers fascinating stories and world-changing ideas. Their tag-line "Ideas worth spreading" certainly captures the point and I highly recommend perusing through their long line of talks as there are topics for everyone. Ontario has an independent TED event called TEDxAlgonquinPark and they recently announced the theme to their 2013 event... "Think Outside". Apply now to be a speaker at the event (Applications close June 7th).
"Your mind, your heart, your soul are longing to explore... to get out there. Longing to experience the unconventional and dance with Mother Nature. There's a place out there with no moulds - no boxes."
