A bunch of mistakes climbers (apparently) make and how to avoid them. Not as concrete and concise as I would like but if you’re willing to filter out the fluff, there’s some interesting information here.
Less concrete and more philosophical than the Self Coached Climber. It hides its interesting insights in a lot of fluff and repeated information.
It starts off with a +20 page diatribe on people being scared of making mistakes which wasn’t very useful to me as someone who already loves making mistakes.
The specificity of his advice (“if you’re a 15 year old climber, do X, if you’re a 16 year old climber, do Y”) reeks of bad editing. Advice this specific has no place in a book like this, because most readers are not going to be 15 year old climbers.
