I like mountaineering too, except for the steeper parts. As opposed to a problem book, this book also provides guidance.

One of my old exercises:
If every task (group) has its disjoint sets of requirements and precautions (likes and dislikes), then form a pair of sets of requirements and precautions (likes and dislikes) an individual should adopt to complete maximum tasks in succession (join most groups at once).
