It seems maybe I'm the last to know but I just found out about TED Talks. TED (Technology, Entertainment, Design) is apparently a conference bringing together people from all different disciplines to share their ideas and inspire each other.
Those talks are available online at www.ted.com and they extremely inspiring. They are each only allowed to be up to 20 minutes so they are very easy to watch or listen to. So far of the ones I've watched these were the most inspiring for me.
