THE SCIENCE OF HAPPINESS 



requires no argument. But how may they be acquired ? 

 This is the question to which all the previous discussion 

 has been preparatory. 



Bearing in mind always the fact that each individual

 alike. By good habits of sleeping I mean such habits 

 as will enable the organism to recuperate most fully

 hours are valuable and to be coveted. 



But this must not be interpreted as meaning that we 

 are to attempt to reduce the period of sleep always to 

 some fixed minimum number of hours. People differ 

 from one another too much to make that possible. Each 

 individual should strive to find what is his own mini- 

 mum period of necessary sleep, and be governed 

 accordingly. 



Remember always that it is better to sleep eight 

 hours if necessary and begin the day with a mind really 

 refreshed, than to attempt to get along with less than 

 is needed. A fully refreshed mind will accomplish 

 more in sixteen hours than the same mind unrefreshed 

 could accomplish in eighteen. 



It is worse than folly to train oneself to arise at five 

 o'clock if the mind is not ready to begin the day's work 

 of thinking at that hour. Better sleep on till eight
