"Not everyone understands what a completely rational process this is, this maintenance of a motorcycle. They think it's some kind of 'knack' or some kind of 'affinity for machines' in operation. They are right, but the knack is almost purely a process of reason, and most of the troubles are caused by what old time radio men called a 'short between the earphones,' failures to use the head properly.

"Mountains should be climbed with as little effort as possible and without desire. The reality of your own nature should determine the speed. If you become restless speed up.
