Sir Steven Redgrave—Winner of 5 Olympic Gold Medals

“In 1997 I was found to have developed diabetes (糖尿病), believing the profession trained for the whole of my life ended, I felt very sorry. Then one of my friends said there was no reason why I should stop training and competing. That was it—the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn’t finished yet. Nothing is to stand in my way.”

Karen Pickering—Swimming World Champion (冠军)

“I swim 4 hours a day, 6 days a week. I manage that amount of work by putting it on top of my diary. This is the key to success—you can’t follow a profession in any field without being well-organized. Make a list of what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”

Kristen Stewart—Actress

“When things are getting hard, a voice inside my head tells me that I can’t achieve anything. Then, there are other distractions, such as family or hobbies. The key is to give most of your attention to one thing. When I feel nervous, it helps a lot to repeat words such as ‘focus’ , ‘calm’, ‘peace’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit and is a powerful psychological(心理学的) tool.”
