You can find many inspirational talks on the web. If you have not discovered TED yet then check it out. Its an amazing resource.
But there are other talks too. Here are my two favorites. I have mentioned them both in the past but if you have not watched them - take the time - they are amazing talks by two people I suspect you know well. And if you have sons or daughters starting out in life encourage them to watch the videos also. I think they may get a lot from them.
