The following video explains that even with lots of practice, it takes genetics to make one a legend, at anything worth doing:
Outliers, http://en.wikipedia.org/wiki/Outliers_(book) explains that to master anything, you need 10,000 hours of focused time.
But, having said that, most people will not bother learning to do any one specific task/talent. It just never occurred to them to give it a try. With a brief training period, you can be more skilled
A simple example is SCUBA diving. According to Scuba-Diving-Smiles.Com(http://www.scuba-diving-smiles.com/how-many-people-scuba-dive.html), 1.5 million people in the USA are certified scuba divers. That is 0.5% of the population of the USA. (They estimated that world wide, at most 6 million people are certified…out of 6 billion people…0.1%) It takes approximately two weeks of training and study and four whole days of being in the water putting your studies to practice to get certified.
What is not readily apparent is the rule of related skills. Miyamoto Musashi wrote in The Book of Five Rings, http://en.wikipedia.org/wiki/The_Book_of_Five_Rings, that a samurai must train in other skills besides swordplay. He encouraged this for numerous reasons, whether implicitlet or explicitly.
One of the benefits of learning other things besides one’s main focus is that the new skills learned are also used in your chosen focus. Learning to snorkel, though very different from SCUBA, will teach you water skills that are used in SCUBA.
Another benefit is to think outside the box by applying skills that othes had not thought of. An example of this is automobile manufacturing. When Henry Ford started making the automobile, everything was made by hand and was done one vehicle at a time. He took a tour of a slaughterhouse and saw how a dis-assembly line meant each worker had o task and then the side of beef headed down the line until it was completely dis-assembled into meat products at a rate far greater than if each man were given a head of cattle and disassembled it himself. An added benefit was that by isolating a man to one task, his skill and quality in that task increased overall quality and consistency
By exposing himself to something new, he was able to reverse the dis-assembly line into an assembly line, taking small parts and each man doing one task to piece together a car…allowing the creation of many more cars per day and of greater and more consistant quality.
In a like manner, when you determine a skill to learn, you will bring skills from your lifthat can apply and will allow you to think outside the norm. However, bear in mind, Henry Ford built cars for years before he put his innovation to work. Learn the basics of a task before you try to innovate in a new skill. If you apply innovation before you learn the basics, those areas where you lack will be hidden by the benefits of the innovation. By hiding areas where you lack, you will not recognize the need to learn them, and you will not become highly skilled or a master of that skill. You will only become “good enough”.
No one ever wrote a book called “Who’s Good Enough”. They write, “Who’s Who”…and they list the masters of any given skill.
