“Because a thing seems difficult for you, do not think it impossible for anyone to accomplish.”

“When the situations seem impossible, the best thing you can do is to think the opposite!”

“We would accomplish many more things if we did not think of them as impossible”

“It is human nature to try hardest to accomplish the very thing we are told is impossible.  Why?  Because innately we know that nothing's impossible.”

“People underestimate the importance of dilligence as a virtue. No doubt it has something to do with how supremely mundane it seems. It is defined as "the constant and earnest effort to accomplish what is undertaken."... Understood, however, as the prerequisite of great accomplishment, diligence stands as one of the most difficult challenges facing any group of people who take on tasks of risk and consequence. It sets a high, seemingly impossible, expectation for performance and human behavior.”

“It is not because things are difficult that we do not dare, it is because we do not dare that they are difficult.”
