Quote by Thomas Kuhn

"The transition between competing paradigms cannot be made a step at a time."

"Discovery commences with the awareness of anomaly."

"Normal science does not aim at novelties of fact or theory and, when successful, finds none."

"No natural history can be interpreted as anything but myth."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
