While this may not be the most eloquent speech it is one that I will remember for a few reasons. Ray Bradbury was conferred an honorary degree by my undergrad. He was unable to come due to an illness but he recorded a
video for us. His presentation starts at about 7:00 minutes in.
To summarize for those that aren't going to watch, he talks about how he didn't go to school because he was poor, but, he went to the library and earned a degree in library. He then talks about how all you need to do is do what you love, and how he did what he loved his entire life, and how that is all that matters.
Keep that in mind, if you go into the working world and don't end up liking what you are doing take time to re-evaluate where you are, and where you have been, and what makes you truly happy, before it becomes too late.
