Ta eph’hemin, ta ouk eph’hemin.

What is up to us, what is not up to us.

Greek saying.


God, give me grace to accept with serenity the things that cannot be changed,
Courage to change the things which should be changed,
and the Wisdom to distinguish the one from the other.

Serenity Prayer


If we do not create and control our environment, our environment creates and controls us.

Marshall Goldsmith


Freedom is the only worthy goal in life. It is won by disregarding things that lie beyond our control.

Épictète



If everything seems to be under control, you’re just not going fast enough.

Mario Andretti
