One possible explanation lies in a concept called brain synchronicity. Essentially, this refers to how well different parts of the brain involved in a task are working together. When synchronicity is high, we’re better able to focus, learn, and perform.
However, over time, as we fall into routines—practicing the same way or playing the same opponents—this synchronicity can decrease. The brain automates familiar tasks, and the activity becomes less mentally engaging.
Introducing novelty into your routine helps re-engage the brain, boosting synchronicity. For instance, focusing on the feel of a new cue or how it performs can momentarily sharpen your attention. But eventually, that too becomes normalized, and synchronicity levels return to baseline.
You don’t need to buy a new cue every month to achieve this. Switching up routines, trying new challenges, playing different opponents, or exploring other games can have a similar effect.
