Let me introduce you to neurons. Your brain cells. Your thoughts activate groups of neurons. Different thoughts activate different neurons. Repeating the same thoughts makes the groups of neurons activate faster and form stronger connections. They form neural pathways. Imagine your brain is a forest. Neural pathways are trails. The more you follow them, the deeper they get. Overthinking comes from deep neural pathways in your brain forest. You overthink as long as they're act
