I recently discovered CreativeMornings, a free monthly breakfast lecture series. Fortunately, they are also recorded, and past meetings can be found on their Vimeo page.
These bite-size lectures (20 minutes each) are perfect for getting the creative juices flowing and hearing from various speakers about topics you might not otherwise discuss in your day-to-day role. The first lecture I watched was by Paul Ormerod an economist, and the topic was money, a topic not often discussed widely within creative circles.
I would highly recommend setting aside some time each month to watch these.
