You have to realize, your thoughts are not really your own thoughts. They percolate in from other places and from other people

— Robert Shiller

“Some people are more impressionable than others. But everyone is a product of the experiences they’ve had, the people they’ve met, the people they’ve observed, the people they’ve read about, and the people around them at any given moment who are shaping their behaviors in good, bad, and ugly ways. That alone explains so much wild behavior in the world.” – Morgan Housel
