How to Be a Winner

Sir Steven Redgrave

Winner of 5 Olympic Gold Medals

“In 1997 I was found to have developed diabetes(糖尿病). Believing my career was over, I felt extremely low. Then one of the specialists 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

“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success — you can’t follow a career in any field without being well-organized. List 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.”

Kirsten Best

Poet & Writer

“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological tool.”
