Not everything is down to genetic predisposition. For example, whether we are a genius or not. It is a massive simplification to say that an individual was born a genius because of their genetic predisposition.
That belief has now been completely refuted. Take Darwin, Einstein or Mozart, for example. These were people who had no genetic predisposition for the things they achieved. They just applied themselves assiduously.
Educationists estimate that a learner needs to spend approximately 10,000 hours studying and practicing before he or she becomes really proficient in a skill. And that was also true of the three aforementioned geniuses. The secret of success is ultimately performing an activity very often and very intensively.
