“Virtue is harder to be got than knowledge of the world”

“Nothing in this world is harder than speaking the truth, nothing easier than flattery.”

“It is necessary, in this world, to be made of harder stuff than one's environment.”

“… nothing in the world is harder than convincing someone of an unfamiliar truth.”

“The tragedy of virtue is that the more obvious, boring, unoriginal, and sermonizing the proverb, the harder it is to implement.”

“Truth is harder to bear than ignorance, and so ignorance is valued more— also because the status quo depends on it; but love depends on self-knowledge and self-knowledge depends on being able to bear the truth.”

“A man's own self is the last person to believe in him, and is harder to cheat than the rest of the world.”

“Knowledge is one thing, virtue is another.”

“It is time to face real world, even if it is harder and painful. I'd rather fly and crash, than just snuggle and sleep.”

“You're really spread out now, you've got stuff all over the WORLD! You've got stuff at home, stuff in storage, stuff in Honolulu, stuff in Maui, stuff in your pockets… supply lines are getting longer and harder to maintain.”
