God is a challenge because there is no proof of his existence and therefore the search must continue.
Donald Knuth
Our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change.
Martin Luther King Jr
Give yourself an even greater challenge than the one you are trying to master and you will develop the powers necessary to overcome the original difficulty.
William Bennett
The challenge to me as a director was for the audience to see the film as going on in a straight line, so that they did not sense all of these break-ups. I did not want a film to be a collage of all these images.
Pedro Almodovar
I believe that we should take every opportunity to challenge the assumption that our European allies are doing us a favor whenever they provide us with the necessary facilities from which to defend their own continent.
Chester Bliss Bowles
Never again clutter your days or nights with so many menial and unimportant things that you have no time to accept a real challenge when it comes along. This applies to play as well as work. A day merely survived is no cause for celebration. You are not here to fritter away your precious hours when you have the ability to accomplish so much by making a slight change in your routine. No more busy work. No more hiding from success. Leave time, leave space, to grow. Now. Now! Not tomorrow!
Og Mandino
You may not ever travel to Maine to see the Furbish lousewort. But the weeds in any patch of natural vegetation issue the same challenge. We have survived, say the weeds, since the Cretaceous. Man is a mere novice in evolution compared with us. He hasn't yet learnt the secret of the weeds: how to create fail-safe communities.
Eric Ashbyâ€
The challenge of modernity is to live without illusions and without becoming disillusioned.
Antonio Gramsci
The new American finds his challenge and his love in the traffic-choked streets, skies nested in smog, choking with the acids of industry, the screech of rubber and houses leashed in against one another while the town lets wither a time and die.
John Steinbeck
The great challenge of adulthood is holding on to your idealism after you lose your innocence
Bruce Springsteen
Gender equality is more than a goal in itself. It is a precondition for meeting the challenge of reducing poverty, promoting sustainable development and building good governance.
Kofi Annan
How you respond to the challenge in the second half will determine what you become after the game, whether you are a winner or a loser
Louis Camuti
The new American finds his challenge and his love in the traffic-choked streets, skies nested in smog, choking with the acids of industry, the screech of rubber and houses leashed in against one another while the town lets wither a time and die
John Steinbeck
There is never time in the future in which we will work out our salvation. The challenge is in the moment; the time is always now
James Arthur Baldwin
