Sometimes you stumble upon someone who's thinking exactly the same as you, only expressing themselves far better.
Here's Isaac Asimov in a 1988 interview with Bill Moyers, in which he explains, among other things, what it'll be like once the internet comes into our homes (sadly he just missed seeing it come about). This bit about his love of learning new stuff really struck a chord for me:
I think it's the actual process of broadening yourself, of knowing there's now a little extra facet of the universe you know about and can think about and can understand. It seems to me that when it's time to die, and that will come to all of us, there will be a certain pleasure in thinking that you had utilised your life well, that you had learned as much as you could, gathered in as much as possible of the universe, and enjoyed it.
