What do Americans look for in a car? I've heard many answers when I've asked this question. The answers include excellent safety ratings, great gas mileage, handling, and cornering ability, among others. I don't believe any of these. That's because the first principle of the Culture Code is that the only effective way to understand what people truly mean is to ignore what they say. This is not to suggest that people intentionally lie or misrepresent themselves. What it means is that, when asked direct questions about their interests and preferences, people tend to give answers they believe the questioner wants to hear. Again, this is not because they intend to mislead. It is because people respond to these questions with their cortexes, the parts of their brains that control intelligence rather than emotion or instinct. They ponder a question, they process a question, and when they deliver an answer, it is the product of deliberation. They believe they are telling the truth. A lie detector would confirm this. In most cases, however, they aren't saying what they mean. -- The culture code.

No matter how much you plan you’re likely to get half wrong anyway. So don’t do the ‘paralysis through analysis’ thing. That only slows progress and saps morale. -- 37 Signal, Getting real

I don’t want to get to the end of my life and find that I lived just the length of it. I want to have lived the width of it as well. ~Diane Ackerman

Whatever you can do, or dream you can, begin it. Boldness has genius, power and magic in it. –Johann Wolfgang von Goethe
