9:21 < Lesson 5 Mental Toughness Section 4 * 4G 4 Use Imaging. Practice for failure. 83% Many champions use imaging. Imaging means visualizing the action you are going to take: shooting a basket or passing a football. Imaging is not just making pictures in your mind. It also involves hearing, feeling, and thinking. Emily Cook, an Olympic skier, used imaging. By imagining the smell of the snow, the wind on her neck, and the roar of the crowd, Cook increased her focus and confidence. She says, "You have to hear it. You have to feel it, everything." |連続 -X Nicole W. Forrester, an Olympian and eight-time Canadian high jump champion, spent hours imaging what she wanted to do. She would even create bad scenarios that could occur,
