If you want to be inspired, take an hour out of your day and watch the video of Randy Pausch giving "the last lecture" (it's the first link on the page). His lecture is also a book that is currently on the best seller list, but trust me the lecture is much better. Like many great people, he has made a difference in this world, not by what he has done, although impressive; but by the way he lived his life. He makes me want to be a better person.
