Suffice to say it's never enough.
When I climbed more, I am more minded to find hard move and the chalenge of new moves attrack me.
I climbed handson echard at canon and the crux is not too hard. You follow a diedral and when it end, you have to change for a left hand crack. It was pumpy, I can't see anything to make the move; and I remember closing my eyes and asking me where I want the missing hole. My hand fall on it instinctively. It was exactly where you need a good hole to make the traverse. As I was climbing more, my instinct was better and I was able to climb harder on sight.
II think that all the move are in 5.7 and lower. So climbing often even easy grade was good for me to push my limit gradually, with a lot of fun when I make it or fail.
