Have you ever observed that we pay much more attention to a wise passage when it is quoted than when we read it in the original author?
Learn to get in touch with the silence within yourself and know that everything in this life has a purpose.
It is easier to exclude harmful passions than to rule them, and to deny them admittance than to control them after they have been admitted.
Ask not what you can do for your country. Ask what's for lunch.
Never eat more than you can lift.
I am not young enough to know everything.
Reveal not every secret you have to a friend, for how can you tell but that friend may hereafter become an enemy. And bring not all mischief you are able to upon an enemy, for he may one day become your friend.
