Iron sharpens iron; scholar, the scholar.

Visualization - it's been huge for me. Your mind doesn't know the difference between imagination and reality. You can't always practice perfectly - my fingers will play a little bit out of tune, or my dance moves might not be as sharp - but in my mind, I can practice perfectly.

The imagination is the spur of delights... all depends upon it, it is the mainspring of everything; now, is it not by means of the imagination one knows joy? Is it not of the imagination that the sharpest pleasures arise?

I visited Jobs for the last time in his Palo Alto, Calif., home. He had moved to a downstairs bedroom because he was too weak to go up and down stairs. He was curled up in some pain, but his mind was still sharp and his humor vibrant.

In sharp contrast to the idea that this stage of life is enviable, we hear high levels of anxiety about getting old, anxieties about health, mobility, access to facilities, simple routine care and attention.

Great literature should do some good to the reader: must quicken his perception though dull, and sharpen his discrimination though blunt, and mellow the rawness of his personal opinions.

God answers sharp and sudden on some prayers, And thrusts the thing we have prayed for in our face, A gauntlet with a gift in it.

I grew up between Detroit and Ghana, and I had to make friends in an instant. It sharpened my wit, and also, just for my own sanity's sake, I felt like I wanted to entertain myself. So I'm going through all these experiences, and I ask myself, 'Is this crazy? Is it? Wait, what's so funny about this?'

As iron sharpens iron, so a friend sharpens a friend.

I think we're struggling with trying to redefine various positions at this point in history. To allow freedom for women, freedom for men, freedom from those sharply defined gender roles.

I discipline churchgoers with godly lessons and sharp words if they do not change their ways. My goal is to open their hearts so that they seek forgiveness.

It's always difficult not playing games and that match fitness and sharpness is something you always lack when you don't get that opportunity.

When you don't play, you really feel the difference of what matches give you. The match-sharpness, the fitness. It's what you need to progress.

Obviously, when you're doing fitness work at a club all week and every week, it's all about specific drills for what you need to do on the pitch. So I'd be doing a different drill to the centre-midfielders. It's all specifically tailored for me. For example, my drills are high speed. It's all about trying to break the line with a sharp sprint.

You want to play as many games as possible, you want to stay sharp, and there is nothing like game fitness.

You're not human if you don't feel fear. But I've learnt to treat fear as an emotion that sharpens me. It's there to give me that edge for what I have to do.

Fear and euphoria are dominant forces, and fear is many multiples the size of euphoria. Bubbles go up very slowly as euphoria builds. Then fear hits, and it comes down very sharply. When I started to look at that, I was sort of intellectually shocked. Contagion is the critical phenomenon which causes the thing to fall apart.

Bereavement is the sharpest challenge to our trust in God; if faith can overcome this, there is no mountain which it cannot remove.

The only faith that wears well and holds its color in all weathers is that which is woven of conviction and set with the sharp mordant of experience.

Sometimes if I'm in my head before a take, I'll just like to reach out to the closest thing to me - the wall or a sharp edge - and just push into it. That way, my physical experience is totally contemporaneous and not in the clouds.

Glamour is an imaginative process that creates a specific emotional response: a sharp mixture of projection, longing, admiration, and aspiration. It evokes an audience's hopes and dreams and makes them seem attainable, all the while maintaining enough distance to sustain the fantasy.

I think I am becoming obsessive-compulsive. David Beckham apparently turns all the Diet Coke cans in his fridge to face the same way every morning, and I nerdily sharpen all the pencils in my pot before sitting down to work.

My nutritionist has done a great job in changing my diet after we established I am allergic to things like gluten - I can't eat pizza, pasta and bread. I have lost some weight, but my movement is sharper and I feel great.

I have never seen a game's graphics look so sharp and clean. The sound design for the game is also unique on the Xbox. The memory on this system allowed us to provide the user with 5.1 Dolby surround sound for home theatre owners.
