Frequent not the company of immodest persons, especially if they be also impudent, as is generally the case; ...these corrupted souls and infected hearts scarcely speak to any, either of the same or a different sex, without causing them to fall in some degree from purity; they have poison in their eyes and in their breath, like basilisks. On the contrary, keep company with the chaste and virtuous; often meditate upon and read holy things; for the word of God is chaste, and makes those also chaste that delight in it.

Have patience with all things, but chiefly have patience with yourself. Do not lose courage in considering your own imperfections but instantly set about remedying them -- every day begin the task anew.

Go in all simplicity; do not be anxious to win a quiet mind, and it will be all the quieter. Do not examine so closely into the progress of your soul. Do not crave too much to be perfect, but let your spiritual life beformed by your duties, and by the actions which are called forth by circumstances.

Be patient with everyone, but above all with yourself. I mean do not be disheartened by your imperfections, but always rise up with fresh courage

Marital intercourse is certainly holy, lawful and praiseworthy in itself and profitable to society, yet in certain circumstances it can prove dangerous, as when through excess the soul is made sick with venial sin, or through the violation and perversion of its primary end, killed by mortal sin; such perversion, detestable in proportion to its departure from the true order, being always mortal sin, for it is never lawful to exclude the primary end of marriage which is the procreation of children.

It matters little how one begins, provided that he be resolved to go on well, and to end well.

You can attract more bees with a spoonful of sugar than a cupful of vinegar.
