“Ambient sounds, especially with words, occupy about 5-10% of your intellectual bandwidth. By wearing ear protectors, you acoustically isolate yourself. This freed up bandwidth can now be focused on the desired task. It s a great deal. Just put on some earmuffs and you become 5-10% smarter.”
“Always maintain the attitude of a student. When a person thinks they have finished learning, that is when bitterness and disappointment can set in, as that person will wake up everyday wondering when someone is going to throw a parade in their honour for being so smart.”
