Initiative of the Year - Finalist_IWSA

The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails. ”           W.A. Ward

Twenty years from now, you will be more disappointed by the things you didn’t do than those you did. So throw off the bowlines. Sail away from safe harbor. Catch the wind in your sails. Explore. Dream. Discover.”            Mark Twain
