I wonder if anyone can verify that the following quotation is actually authentic. "Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor.Catch the trade winds in your sails. Explore. Dream. Discover." I am familiar with most of Twain's work and the "Explore. Dream. Discover doesn't sound like him. Any help would be appreciated -- I've already searched Rasmusssen and most of my other Twain collection. Thanks.
