“If I only had three words of advice, they would be, 'Tell the Truth.' If got three more words, I'd add, 'all the time.' People lie for lots of reasons, often because it seems like a way to get what they want with less effort. But like many short-term strategies, it’s ineffective long-term. You run into people again later, and they remember you lied to them. And they tell lots of other people about it.”
