1Many students think memory is a gift that you either have or not.

2In fact, memory works more like a muscle that grows with training.

3The brain forgets new information quickly if we never look at it again.

4That is why reviewing something the next day helps so much.

5A review after one week makes the memory even stronger.

6Another review after one month can fix it in your mind for years.

7Sleep also plays an important role in keeping memories safe.

8During sleep, the brain sorts the things we learned during the day.

9So students who sleep well often remember more than those who study all night.

10Good memory is mostly about smart timing, not natural talent.
