As quoted in Honor Your Gifts (2007) by Dona M. Deane, p. 199.
Variant: But there is suffering in life, and there are defeats. No one can avoid them. But it's better to lose some of the battles in the struggles for your dreams than to be defeated without ever knowing what you're fighting for

General Quotes

This writing can be less demanding should I allow myself to indulge in the usual manipulating game of role creation. Fortunately for me, my self-knowledge has transcended that and I've come to understand that life is best to be lived — not to be conceptualized. If you have to think, you still do not understand.

κρεῖσσον γὰρ εἰσάπαξ θανεῖν
ἢ τὰς ἁπάσας ἡμέρας πάσχειν κακῶς.
Variant translation by John Stuart Blackie (1850):
"Life and life's sorrows? Once to die is better
Than thus to drag sick life."
