I failed on a climbing problem eight times before realizing I was climbing as high as I knew I could and then letting go. On my next try I climbed with no thought of failure and reached the top. We cannot know what we can do in advance. The only way to find out is to go all-out trying, thinking only of success.
Royal RobbinsWhen it's been a long day of climbing, and I feel like I can't go any farther, I concentrate on the next three feet. And then the next three feet; and then the next three feet. Pretty soon, I'm at the top.
Royal RobbinsThe terrible thing about free soloing difficult routes that are within one's capacity, is the chance that faced with ultimate danger and need for ultimate self-control, one's nerve might fail and cause an error. That's irony of it - that fear could short-circiut skill, that one would die as a direcy result of being afraid to die.
