When you drive a car slow then you will notice that you are listening to music, podcast or talking to someone on the phone. it’s easy for you to multitask when you’re driving slowly but notice the F1 drivers. They do nothing else while driving there race cars as the speed of the car makes you wanna focus on one thing only – that is driving the car. The same applies to reading. Your mind starts to daydream and think a lot and this is because you’re reading too slowly and you have a lot of time to think about other things and people which takes away from your focus.
