For all things in this life that thou desireth, thou shalt also pay plenty, and for the wisdom of experience, no less. Advice from the multitudes costeth nothing and usually worth as much. In the books though mayest read what to do and when, but only the voice of experience may tell thee why and how, else reading of what and when shall but plague thee with somke. God maketh the earth rotate endlessly without bearing or oil, but not thy diesel. Curse not thine engine when it turneth not.
Curse rather thine own neglect.
With gauges and mikes be though ever busy. The eternal eye watcheth universal operations, but thou shalt not rely upon it as to thy diesel. Thine own vigilance is the price thou payest for thy job.
