“Worry can become like a bad habit of the mind. The rule of neuroplasticity—that our brain keeps changing based on our repeated activity—says that whatever we do a lot we will get better at. So if we worry a lot, we will get really good at worrying.” In other words, once you start worrying about something, it can be hard to stop.

neural pathways we don’t use die off over time. What makes our brains hold on to these pathways — and create more — is not simply repeating the same things we’ve learned over and over again, but continually taking on difficult problems.

So here is the take-home lesson. We have to seek novelty, because this is what lays down new memories in the brain.
