Have you ever experienced a slow computer? The solution is often to clear the cache, which rids it of unnecessary data and permits it to function more efficiently.

The same principle applies to your brain.

Self-talk is overwhelming

“Self-talk” refers to the running commentary in our brain that stays with us throughout the day and often into the night. It can be positive or negative.

Our self-talk tilts towards the negative, due to our negativity bias. While negativity bias can be useful (like when it discourages us from taking unacceptable risks), our tendency to overweight the negative can harm our emotional state and even make us depressed.

The amount of our self-talk (whether positive or negative) is overwhelming. Experts estimate we average 2,100 to 3,300 thoughts per hour (50,000-80,000 thoughts per day).

That’s a lot of input for the brain to process, especially when it’s also engaged in many other activities requiring perceiving, evaluating and interacting with the world around us.
