Immoral habits are like shackles: They deprive man of his moral freedom, and forcibly keep him in the stinking swamp of the passions.
St. Ignaty Brianchaninov
He who is conquers himself in the little things will also do so in the great ones.
Abba Isaiah
There is no tyranny so unbearable as a habit; it is with reason that it is called second nature.
St. John Chrysostom
It is impossible to surmount the great if one does not conquer the insignificant.
St. Isaac of Syria
