“It takes courage… to endure the sharp pains of self discovery rather than choose to take the dull pain of unconsciousness that would last the rest of our lives.”

The Caesars (c. 361)
Context: "It is the season of the Kronia, during which the god allows us to make merry. But, my dear friend, as I have no talent for amusing or entertaining I must methinks take pains not to talk mere nonsense."
"But, Caesar, can there be anyone so dull and stupid as to take pains over jesting? I always thought that such pleasantries were a relaxation of the mind and a relief from pains and cares."
"Yes, and no doubt your view is correct, but that is not how the matter strikes me. For by nature I have no turn for raillery, or parody, or raising a laugh."

They are discouraged from expressing hurt, sadness, fear, disappointment, insecurity, embarrassment and other such emotions. It is because males are thought to be and are expected to be tough that they may be treated more harshly. Thus, corporal punishment and various other forms of harshness may be inflicted on them but often not on females, who are purportedly more sensitive.

My Day (1935–1962)
Context: It takes courage to love, but pain through love is the purifying fire which those who love generously know. We all know people who are so much afraid of pain that they shut themselves up like clams in a shell and, giving out nothing, receive nothing and therefore shrink until life is a mere living death. (1 April 1939)
