Thomas a Kempis

First keep peace with yourself, then you can also bring peace to others

Love flies, runs, and rejoices; it is free and nothing can hold it back

And when he is out of sight, quickly also is he out of mind.

It is much safer to obey, than to govern

Be not angry that you cannot make others as you wish them to be, since you cannot make yourself as you wish to be

Remember that lost time does not return.

Never be entirely idle; but either be reading, or writing, or praying or meditating or endeavoring something for the public good

What difference does it make to you what someone else becomes, or says, or does? You do not need to answer for others, only for yourself.

It is no little wisdom for you to keep yourself in silence and in good peace when evil words are spoken to you, and to turn your heart to God and not to be troubled with the judgment of others
