Thus it is this power which constitutes the real distinction between a physical and a moral life, and that forms the primary basis of individual character.
In the Bible praise is given, not to the strong man who "taketh a city," but to the stronger man who "ruleth his own spirit." This stronger man is he who, by discipline, exercises a constant control over his thoughts, his speech, and his acts.

Nine-tenths of the vicious desires that degrade society, and which, when indulged, swell into the crimes that disgrace it, would shrink into insignificance before the advance of valiant self-discipline, self-respect, and self-control.

By the watchful exercise of these virtues, purity of heart and mind become habitual, and the character is built up in chastity, virtue, and temperance.
The best support of character will always be found in habit, which, according as the will is directed rightly or wrongly, as the case may be, will prove either a benignant ruler or a cruel despot.

We may be its willing subject on the one hand, or its servile slave on the other.

It may help us on the road to good, or it may hurry us on the road to ruin.
Habit is formed by careful training.
