Rigidity, self-denial.
“Those who are very strict in their way of living; they deny themselves many of the joys and pleasures of life because they consider it might interfere with their work. They are hard masters to themselves. They wish to be well and strong and active, and will do anything which they believe will keep them so. They hope to be examples which will appeal to others who may then follow their ideas and be better as a result.” – Dr. Edward Bach
