Quotes:
• There is a time to deliberate… and a time to act. Learn to recognize which is which, and act accordingly. — Douglas Clark Merrill (1970-) American technologist
• The great enemy of the truth is very often not the lie, deliberate, contrived, and dishonest; but the myth, persistent, persuasive, and unrealistic. — John Fitzgerald Kennedy (1917–1963) 35th president of the United States
