"I believe that there were four critical components needed to complete this quest—an understanding and supportive spouse, time, financial resources and connections. Save the understanding wife, I would have been hard-pressed to have the other three 100 years ago. One hundred years ago, my time would have been totally consumed with obtaining the basic requirements of food, shelter and clothing. Today so many more of us have much more time for leisure, more disposal income, and a much larger circle of friends and associates than we would have had. For all this current talk about tribalism, there is so much more that links us than separates us. Yes, I really do believe that ours is a world that is better today than it ever was. I also believe that in another hundred years, it will be even better... Our imaginations, our creativity, and our belief in things bigger than ourselves will make it so."
