Remember, the definition of focus is paying attention to what you are trying to learn in the present moment.
But it is difficult to be focused in the present moment when you are trying to study in a room or place filled with a lot of distractions.
But, the good news is that because of your brain’s extraordinary neuroplastic power, you can improve your ability to focus even if you are in a place with some distractions.
And, of course, the more you practice focusing with some distractions the better your focus will become.
