Good ideas sometimes come from carrying one hobby into another
New ideas arrive when something you learn now connects with something you learned years ago.

GP, who says he has a neurodivergent mind, puts it this way: “One of my favorite things about deep dives is when two unrelated things suddenly connect.”
“You're learning about one subject and something clicks with something you learned three years ago,” he says. In his words, “Creativity is not always pulling something out of thin air. Sometimes it's noticing that two things that were never introduced should probably meet.”
In his telling, your brain has just completed a circuit. He says, “Nobody else in the room may care.” You care because the connection landed for you. He sums up that feeling as, “Pattern, connection, recognition,” and, “Oh, that's why.”
The link, he argues, is that you pick up skills by following an interest. His example is microphones: “You thought you were learning about microphones and now you understand acoustics, signal flow, room treatment, electronics, performance technique.” He says, “And sometimes the skill you picked up in one rabbit hole turns out to be useful somewhere completely different,” carried from one interest into another.
His examples of carrying an idea are plain. He says, “You hear one style of music and wonder what it would sound like somewhere else. You learn how one industry solves a problem and realize another industry could borrow the same idea.” He adds, “Sometimes you come back with absolutely nothing useful, but you had a great time.”
Questions people ask
What does he mean by a rabbit hole?
He means an intense, curiosity-led dive where one question leads to another. You start wanting an answer and end up wanting context, history and what everyone missed. You may look up who made something, what came before it and whether anyone has argued about it for years.
How does he suggest keeping a deep dive from taking over the day?
He suggests giving curiosity an edge. Set a timer, save links for later, and keep a note called things you want to know more about. The point is to capture the interest now and return later, so you are saying not yet rather than no.
What if a deep dive leads nowhere?
He says that happens and it can still be worth it. Not every dive has to be productive or connect to something else. If the important things got done, enjoying the dive for its own sake is fine.
