A few decades ago, multitasking was considered a strength. But over time, research has proven that multitasking impacts our ability to do deep work and reduces our output quality.

The reason behind this is switching cost.

When we switch between tasks often, our ability to focus deeply is lost. We have to get out of the mental zone of one thing, and enter a new zone of doing something else.

When we do this repeatedly, we carry over our thoughts and emotions from the previous task into the new task. This affects the quality of our focus, attention and overall outcome.
