writing

Writing your worries down fixes your focus.

In a 2011 study, college students who wrote about their anxieties before an exam performed significantly better than those who did not.

Writing acts as a cognitive outlet, offloading the memory burden of stressful thoughts. By externalizing the worry, you free up the mental capacity required for complex problem-solving.

Your brain performs better when it is not carrying the mental load.
