πŸ’Ž On how we evaluate ourselves by comparing to known references (cognitive dissonance)

Leon Festinger and Merrill Carlsmith of Stanford University once asked their students to carry out an hour of excruciatingly boring tasks. They then divided the subjects into two groups. Each student in group A received a dollar (it was 1959) and instructions to wax lyrical about the work to another student waiting outside – in other words, to lie. The same was asked of the students in group B, with one difference: they were given $20 for the task. Later, the students had to divulge how they had really found the monotonous work. Interestingly, those who received only a dollar rated it as significantly more enjoyable and interesting. Why? One measly dollar was not enough for them to lie outright; instead they convinced themselves that the work was not that bad. Just as Aesop’s fox reinterpreted the situation, so did they. The students who received more didn’t have to justify anything. They had lied and netted $20 for it – a fair deal. They experienced no cognitive dissonance.

πŸ’Ž On the benefits of brevity (sell your idea or your dream in 10 to 15 minutes)

Let’s put this in perspective. Abraham Lincoln inspired generations in a speech that lasted two minutes. John F. Kennedy took 15 minutes to shoot for the moon. Martin Luther King Jr. articulated his dream of racial unity in 17 minutes. Steve Jobs gave one of the most famous college commencement speeches of our time at Stanford University in 15 minutes. If you can’t sell your idea or your dream in 10 to 15 minutes, keep editing until you can.

Ideas don’t sell themselves. Be selective about the words you use. If they don’t advance the story, remove them. Condense, simplify, and speak as briefly as possible. Have the courage to speak in grade-school language. Far from weakening your argument, these tips will elevate your ideas, making it more likely you’ll be heard.
