More opportunities to speak up:

Orient yourself forward into action, not backward, away from errors. Speak down: “Don’t hold your breath.” Speak up: “Remember to breathe.”

Does climbing present problems or opportunities? When you speak down, you emphasize problems: “This looks gripping.” Speak up to focus on opportunity: “What can I learn from this runout section?”

You don’t have to do anything in climbing. Speak down: “I have to get better at crack climbing.” Speak up: “I choose to practice crack climbing.”

Don’t try—do. Create goals that relate to effort and actions (which you can control), and not end results (which you can’t). Speak down: “I’ll try to do it without falling.” Speak up: “When I start to get pumped, I’ll shift more focus to my footwork and keep moving up.”
