Human brain has limited working memory.

To plan better for the next day at work , thinking more about to-dos constantly results in high amount of strain on the brain by triggering what is known as “rehearsal loops“.These constantly play on in our mind reminding us of the action items.

Rather than subjecting ourselves to duress , the much easier option to write down the list of to-dos in Post-It notes to reduce the pressure on brain for better performance.

Eric Barker’s book , Barking Up the Wrong Tree makes a mention of the same.
