I’m not saying there’s no such thing as genius. But if you’re trying to choose between two theories and one gives you an excuse for being lazy, the other one is probably right. Paul Graham

Someone trying to live well would seem eccentrically abstemious in most of the US. That phenomenon is only going to become more pronounced. You can probably take it as a rule of thumb from now on that if people don't think you're weird, you're living badly.

Paul Graham

One of the most intelligent case studies in design is the Chinese tea cup. They’re made without handles simply because if it’s too hot to touch, it’s too hot to drink.

Humans naturally want to add more. Add a cardboard sleeve, add a warning on the outside of the cup, add a handle. The result of all these things never cools down the actual contents.
