Life's journey is not traveled on a freeway devoid of obstacles, pitfalls, and snares. Rather, it is a pathway marked by forks and turnings. Decisions are constantly before us. To make them wisely, courage is needed: the courage to say, 'No,' the courage to say, 'Yes.' Decisions do determine destiny. The call for courage comes constantly to each of us. It has ever been so, and so shall it ever be.
Whether we like it or not, we are all on a journey, a Quest if you will, every day of our lives, and the path we must take is full of perils, and our destiny can never be predicted in advance.
You can just keep going and going and going, and you never get to the end of it because there is no end. The ending is a beginning. If you feel like that, then you accept that wherever you have to stop on this journey, you continue in some other form somewhere else.
We will build new ships to carry man forward into the universe, to gain a new foothold on the moon and to prepare for new journeys to the worlds beyond our own.
It was a pleasure and a privilege to walk with him [H.D. Thoreau]. He knew the country like a fox or a bird, and passed through it as freely by paths of his own.
Along the road of life are many pleasure resorts, but think not that by tarrying in them you will take more days to the journey. The day of your arrival is already recorded.
Science is an intellectual journey, and to me, it's not the destination, it's the journeyto get there. It's a way of thinking and it's an intellectual curiosity, a desire to know how the world works, and to know what the fundamental principles of the world are, and to know our place in it. I think once we stop asking questions like "what is the age of the universe," or "how are the instructions of DNA carried out on a microscopic level," once we stop asking questions like that, we're dead.
