Dago: Why should i focus on projects over categories? This is really one of the biggest mind set shifts and shifts in behavior that i see people in my course half. Here's how it works. Most people, when they think of knowledge, they think of information. But a much better analogy, fr for professionals, for students, for people who are our intaking knowledge and then creating things, is a factory. A factory has a certain quality that is highly relevant to us, which is that it's linear. An output is really everything. When you create something, when you have real concrete output, people can't argue with that. They can't pretend it doesn't exist.
