I brought a Border Collie back home to Vancouver from Wales - where some of my ancestors are from - and needed to challenge him in other ways than just being my pet. So I investigated sheep herding and took a few lessons and decided I was probably learning more than my dog!

We must all learn a good lesson - how to live together. That is the new challenge of the new world... learning to co-exist and not co-annihilate.

It is always good to explore the stuff you don't agree with to try and understand a different lifestyle or foreign worldview. I like to be challenged in that way and always end up learning something I didn't know.

History has shown that one cannot legislate a culture of integrity. And yet one of the paramount responsibilities and challenges of corporate leadership is to ensure such a culture.

I think that if Republicans are given the reins of leadership in the House or Senate or both we will have to govern in a way - at least put forward solutions whether or not the president goes along with them or not that deal with these long-term challenges.

There would not be enough talent that's educated developed and ready to take on the next leadership challenge and it would cap our growth. Now we've put programs in place not to have that happen but that could be a weakness.

Overall the challenge of leadership is both moral and one of developing the characteristics that make us respected by one another.

These past years as we have been recovering and given our city a rebirth we have been encouraged by our faith knowledge and steadfast belief that we will pull through. There will be challenges and setbacks as there have already been but we will continue and we the citizens of New Orleans will prevail in bringing our city back.

Historic changes and challenges. Breakthroughs in human knowledge and opportunity. And yet for vast numbers across the globe the daily realities have not altered.

Poverty and lack of knowledge must be challenged.

I feel like I've reached an age where I can relax a little bit with the knowledge of what I've been through take all that experience and use it. I love the challenge of trying to get back to where I've been and beyond it.

The apple cannot be stuck back on the Tree of Knowledge once we begin to see we are doomed and challenged to seek the strength to see more not less.

Knowledge has to be improved challenged and increased constantly or it vanishes.

It is difficult if not impossible to argue that laws written in the 1970s are adequate for today's intelligence challenges.

In these troubled uncertain times we don't need more command and control we need better means to engage everyone's intelligence in solving challenges and crises as they arise.
