We're being challenged to do something so profound, it's unprecedented in the history of our species, and there couldn't be more at stake. It's not even our species at stake; it's the whole dream of life on earth that's taken 4.5 billion years to realize - all this beautiful pastoral life on earth.

Our Prophet was a radical too- he fought against the injustices of his community and challenged the feudal order of his society, so they called him a radical. So what? We should be proud of that!

Abu Bakar Bashir

To grow, people need to be challenged.

Adam Grant

What to do with a leading business that's challenged by a new technology wave without hurting an existing profit stream? The single greatest example of recent memory is Apple's willingness to decimate iPod sales by incorporating all the category-defining product's features into a new gizmo, the iPhone.

Adam Lashinsky

Coach Parcells challenged me a lot in my rookie year, and not just in games. Almost every day in practice, he'd stand right beside me as he called for the field-goal team to take the field.

Adam Vinatieri

I've had journalists asking me, 'What do we call you - is it handicapped, are you disabled, physically challenged?' I said, 'Well hopefully you could just call me Aimee. But if you have to describe it, I'm a bilateral below-the-knee amputee.'

Aimee Mullins

I'm at a place where I want to have fun. I want to be challenged. I want to love the people I work with and continue to appreciate being in the position to work and play and explore.

Aja Naomi King

I have serious hearing loss. I'm challenged if I don't have my hearing aids in.

Al Jarreau

Nowadays people don't know how to handle it if all the ends aren't tied up and they're not told what to think in films. And if they're challenged, they think it's something wrong with the film.

Alan Cumming

Obviously I was challenged by becoming a Naval aviator, by landing aboard aircraft carriers and so on.

Alan Shepard

If men were meant to be a dominant power, men would be on this earth by themselves. So, I don't understand when women's rights are challenged - because you're talking about human rights. You talk about subjugating an entire culture that we heavily depend on for everything we need for survival.

Aldis Hodge

I like reading things where someone's looked at what I do with some honesty, and maybe been challenged by it, and they have something to say that shows they've thought about it, even if they don't necessarily like it.

Aldous Harding

One doesn't want to feel too contented; you have to feel challenged by the music.

Alex Lifeson

I love being challenged, goofing off, and lots of passion.

Alexis Ren

To be challenged means to strive. I'm almost certain that's true.

Alfred Molina

'Next to Normal' has challenged me as an actor because of how complex Diana is. And that's got me hungry for another character like that in a non-singing role because it would be interesting to express that same intensity in a different way.

Alice Ripley

Coronavirus has challenged daily life in Britain in a way not seen for generations.

Alok Sharma

I have always been very rebellious and gone against the grain. I've always challenged the standards set before me.

Amber Heard

I think no actor should be ever satisfied because there is always something new to do, something fresh to get challenged by.

Amitabh Bachchan

I think that it's important that actors keep getting challenged every day. For every creative person, it's a terrible moment when they say they have done all they want to do.

Amitabh Bachchan

To be honest, I don't think I ever had thought I had to be successful. I just saw a need and I liked to be challenged, that's my personality.
