Repetition can be considered the tool for deep and lasting impression. When you were in nursery school for instance, you learnt the rhyme Twinkle, Twinkle Little Star and you have not forgotten it since then. Why? Because you sang it so many times it rang in your head. You recited the ‘Times Table’ several times a week now you do not need to think too hard to answer the mathematical equation (2×3)x(4+5).
There is a theory that an expert is someone that has spent a minimum of 10000 hours on a specific subject area or skill. This theory of experts surprisingly does not refer to the age of the expert but to the time spent on the subject. A child as young as two is already theoretically capable of reaching the 10000 hour mark. The key is talent and repetition.
Have you ever tried practicing the concept of repetition in more advanced academic tasks than your regular Multiplication Table? Do you realize that if you are studying mathematics in the university and your decide to solve the same quadratic equation 20 times you will discover things that will impress the technique on your brain; the very same equation.
As a literary student, if you read the same book 20 times over, at some point you will be able to tell the story without looking at the book. That is what has happened with certain religions that make it a practice for their children to memorize their scriptures at a very early age. The indoctrination effects of this practice can only be broken by the Almighty.
In the workplace, it is the same effect. The Human Resource question concerning your years of experience simply refers to how much time you have spent on a particular role. This means how many hours you have spent doing a set of similar tasks. Generally, people gain experience involuntarily but the effects of experience gained over years on a particular skill can be deliberately reproduced by focusing on that task not for years, but for hours. 10000 hours.
