Quotations are a recognizable piece of text that made an impression on us and at the same time reminds us of a specific memory or feeling. I have a file in Evernote with my favorite quotes. Here are a few: "That which can be asserted without evidence, can be dismissed without evidence." - Christopher Hitchins/Carl Sagan(?)
"Extraordinary claims requires extraordinary evidence." - Carl Sagan
"Ignorance more frequently begets confidence than does knowledge" - Charles Darwin
"Those who are heartless once cared too much" - Daisy Lowe
"If you want to set off and go develop some grand new thing, you don't need millions of dollars of capitalization. You need enough pizza and Diet Coke to stick in your refrigerator, a cheap PC to work on and the dedication to go through with it." - John Carmack
"Programmer - an organism that turns coffee into software." - Anonymous
"I have never let my schooling interfere with my education" - Mark Twain
