when you're passionate about a topic, want to know the answer to a question or need to solve a problem, your brain is primed to learn. Encounter the same material in a different situation and you're far less likely to learn. And it doesn't matter how many different topics you cover. What matters is how deep you go into the topics that matter to you. You have more of a chance of actually coming up with some new and useful, instead of merely rediscovering or relearning what others already came up with.
