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
