Like our physical bodies, our memory becomes out of shape. As children, we are constantly learning new experiences, but by the time we reach our 20s, we start to lead a more sedentary life both mentally and physically. Our lives become routine, and we stop challenging our brains, and our memory starts to suffer.

Reading has helped motivate me to become a spokesperson for programs like the WrestleMania Reading Challenge. It has motivated me to become more involved in my community and to keep learning new things.

Many comedians and comedy writers have shared the childhood experience of learning to joke to protect themselves from neighborhood bullies when challenge or physical defense were not among the sensible options.

In times of uncertainty, employees crave clarity. As a leader, you won't always have all of the answers - no one expects you to - so you must be open to listening and learning from others. Once you understand a particular challenge and outline the options, you have to be confident in making bold and optimistic decisions.

Arab civilizations had been of an abstract nature, moral and intellectual rather than applied; and their lack of public spirit made their excellent private qualities futile. They were fortunate in their epoch: Europe had fallen barbarous; and the memory of Greek and Latin learning was fading from men's minds.

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.

Sailing is the closest I can get to nature - it's adrenaline, fear, a constant challenge and learning experience, an adventure into the unknown. And of course there is nothing better than wearing the same T-shirt for days and not brushing my hair for weeks.

I know those challenges that come up from time to time in life are our little learning tools, our little steppingstones. If we didn't have those things in our life, how would we learn anything? We would just be walking around like nothing. We need those obstacles in our life because I know one thing - I'm a much better person for them.

Why would I be willing to challenge my Republican leadership? Because my allegiance will always be to the Constitution and the American people first and foremost, not to my political party.

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.

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.

I feel fantastically excited that we have a leader who fought for the leadership without compromising his quite challenging view that the party has to change.

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

An important part of leadership is being able to hold two things in your mind at once: Dealing with the reality, whatever it may be, and focus on hope for the future. Any leader helping an organization through challenges needs to be able to do both.

Leadership is all about taking people on a journey. The challenge is that most of the time, we are asking people to follow us to places we ourselves have never been.

Leadership cannot just go along to get along. Leadership must meet the moral challenge of the day.

I want to deploy the leadership to meet the challenges that face us and to restore America's greatness.

True leadership knows not to go to extremes but knows how to confront and appreciate challenges.

A good cult delivers on its promises. A good cult nourishes the needs of its members, has transparency and integrity, and creates provisions for challenging its leadership openly. A good cult expands the freedoms and well-being of its members rather than limits them.

We are looking for a set of personal characteristics that predict success, the first and foremost of which is perseverance in the face of challenges. We also look for the ability to influence and motivate others who share your values, strong problem-solving ability, and leadership.

Because I've spent most of my life with such a beautiful, talented, challenging female, I feel I've gained - and am still gaining - a great deal of knowledge about the feminine mystique and about personal relationships - knowledge which is so important to a writer.

I'm just grasping everything, getting as much knowledge as I can, and continuing to learn and not being afraid to take challenges and actually take action.

I don't have any particular recipe. It is the reason why doing research is challenging as well as attractive. It is like being lost in a jungle and trying to use all the knowledge that you can gather to come up with some new tricks, and with some luck, you might find a way out.

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.
