I have developed a podcast called the Ten-Minute Entrepreneur as well as a vlog entitled Developing The Entrepreneur Within. Sean also hosts webinars and speaks at events relating to entrepreneurship. In this episode, Brad and Sean discuss all the fundamentals and more about being a true entrepreneur. They discuss what it means to do two things at once so you can never depend on that second job again.  Sean made the decision a while ago that he only wanted to work for one person– himself. Listen in to this and understand that you have to want it and if you do, you will be very successful. Visit www.seancastrina.com for more information about him!
