Did you know that having a good memory depends a lot on your ability to concentrate?
Focusing one hundred percent on something makes it much easier to retrieve it later. Evidence suggests you are better to have a short, full-focused study session and a break, than a longer session interrupted by distractions such as phone calls, social media posts, the TV in the background or even your own thoughts.
The brilliant news is that concentration—short and sharp or long and intense—is a skill you can build up the same way an athlete builds up their fitness and sporting skills.
