There are some great resources for learning about entrepreneurship such as This Week in Startups, a weekly show by founder of Weblogs Inc and Mahalo – Jason Calicanis. He hosts successful entrepreneurs and provides great advice.
There is also a great lecture series by Stanford on entrepreneurship that are all available to listen to.
I also enjoy the podcast Venture Voice, which has some great guests although host Gregory Galant hasn’t been posting as many new shows lately.
Here is a great presentation by Guy Kawasaki where he presents his unique and entertaining words of wisdom. Interesting fact: Guy was offered an interview for position of CEO of Yahoo in the early days of the company but turned it down because he didn’t want to commute an hour each way.
