It is often argued that genes play an important role in imparting intelligence to a human being. The combination of genes decides the intelligence levels and the talents one possesses. This is the reason that all individuals are not born with the same level of intellect. There are instances wherein the individuals find it very easy to learn a particular skill and to master that skill as an expert within a minimum amount of time. It is often said that genius is born. This is true to some extent since there are instances where an individual, in spite of putting in hours of hard work was not able to reach the desired level of expertise. An expert has to have a certain level of intelligence to master a particular trait. The geniuses have a spark but that spark needs to be kindled. It is argued that for a person to be a genius, he should have an inclination towards a particular trait. He should have that minimum amount of expertise required to master that trait. Thus it is sometimes said that geniuses are born (Padgett & Seaberg, 2014).
Psychologists like K. Anders Ericsson, conducted a study where he asked the violinists playing in an elite music academy to estimate the time they invested to do the practice since they started playing violin. The best group said that they had invested close to ten thousand hours of practice. The same question was asked to a lesser known group of violinists and the hours of practice which they had put in was far less than the accomplished group. Thus Ericsson concluded that a person needs at least ten thousand hours of practice to become an expert. However the recent researches have shown that ten thousand hours is not a magic number. Few of the individuals need to put more than ten thousand hours of practice to achieve expertise.
