Howard Hathaway Aiken:
"Don't fret yourself about people trying to take your ideas from you. Most ideas aren't that original, and, when they are, they are greatly disliked by the majority of people.
"Don't worry about people stealing your ideas. If your ideas are any good, you'll have to ram them down people's throats.
"What matters more is what you do with your ideas, not the ideas themselves."
