[Q]: Article: The red crab lives on Christmas Island in the Indian Ocean and has been found nowhere else in the world. But on its homeland it is a very significant species -- some 120 million individuals cover the rain forest floor and play a major role in determining the structure of the ecosystem. These large crabs are active during the day but prefer to stay in the shade and can die in the heat of direct sunlight. They feed on fallen leaves, seeds, fruits and flowers, recycling nutrients and helping to determine the spread and composition of native plants. Most of the year the red crabs live in the holes they dig throughout the forest. During the dry season they hide in these shelters to keep their body wet and remain there for two to three months. But when wet season returns in October or November they begin a legendary mass migration to their seaside breeding grounds, moving in color1ful wave that wash over all obstacles like roads (including special passages and some closed roads built for the red crab) and even seaside cliffs. The annual migration is also closely tied to the lunar schedule. The crabs arrive at the coast and breed at such a time that the females can produce eggs and develop them in caves for a dozen or so days before carrying them into the sea exactly when high tide turns between the last quarter and new moon. During this period sea level on the beaches varies the least and offers an easier approach, which is so important that if the weather delays the migration crabs will put off laying eggs until the next lunar month. Red crab eggs grow right away, and the young live in the sea for a month before returning to the coast, changing into air breathers, and slowly returning inland to begin the cycle once again.

[Q]: Article: Give it five minutes I used to be a hothead. Whenever anyone said anything, I'd think of a way to disagree. I'd push back hard if something didn't fit my world-view. It's like I had to be first with an opinion -- as if being first meant something. But what it really meant was that I wasn't thinking hard enough about the problem. The faster you react, the less you think. Not always, but often. This came to a head back in 2007. I was speaking at the Business Innovation Factory conference in Providence, RI. So was Richard Saul Wurman. After my talk Richard came up to introduce himself and compliment my talk. That was very generous of him. He certainly didn't have to do that. And what did I do? I pushed back at him about the talk he gave. While he was making his points on stage, I was taking an inventory of the things I didn't agree with. And when presented with an opportunity to speak with him, I quickly pushed back at some of his ideas. I must have seemed like such an asshole. His response changed my life. It was a simple thing. He said "Man, give it five minutes." I asked him what he meant by that? He said, it's fine to disagree, it's fine to push back, it's great to have strong opinions and beliefs, but give my ideas some time to set in before you're sure you want to argue against them. "Five minutes" represented "think", not react. He was totally right. I came into the discussion looking to prove something, not learn something. This was a big moment for me. Richard has spent his career thinking about these problems. He's given it 30 years. And I gave it just a few minutes. Now, certainly he can be wrong and I could be right, but it's better to think deeply about something first before being so certain you're right. There's also a difference between asking questions and pushing back. Pushing back means you already think you know. Asking questions means you want to know. Ask more questions. Learning to think first rather than react quick is a life-long pursuit. It's tough. I still get hot sometimes when I shouldn't. But I'm really enjoying all the benefits of getting better. If you aren't sure why this is important, think about this quote from Jonathan Ive regarding Steve Jobs' reverence(respect) for ideas: And just as Steve loved ideas, and loved making stuff, he treated the process of creativity with a rare and a wonderful reverence. You see, I think he better than anyone understood that while ideas ultimately can be so powerful, they begin as fragile, barely formed thoughts, so easily missed, so easily compromised, so easily just squished. That's deep. Ideas are fragile. They often start powerless. They're barely there, so easy to ignore or skip or miss. There are two things in this world that take no skill: 1. Spending other people's money and 2. Dismissing an idea. Dismissing an idea is so easy because it doesn't involve any work. You can scoff at it. You can ignore it. You can puff some smoke at it. That's easy. The hard thing to do is protect it, think about it, let it marinate, explore it, riff on it, and try it. The right idea could start out life as the wrong idea. So next time you hear something, or someone, talk about an idea, pitch an idea, or suggest an idea, give it five minutes. Think about it a little bit before pushing back, before saying it's too hard or it's too much work. Those things may be true, but there may be another truth in there too: It may be worth it.
