I love this site, and if you haven't heard of it, I highly suggest you take some time to look through all the talks. I'm more than certain you can find something interesting, and I suppose this thread is to discuss your favorite TED talks.
Basically, TED is a site with tons of videos of presentations people have given sharing ideas about technology, business, design, science, etc... Please please please check them out, and post your favorite talks here for other people to take a look at.
I'll start by posting my absolute favorite talk, by Simon Sinek. It's called "How Great Leaders Inspire Action", i believe. Check it out
here.
Some of the ideas investigated in these presentations are truly eye-opening, and a lot of them may delve into a topic some of you may be considering as a career, or as an area of interest in the future.
