Story time (written in hindsight, because I didn't expect to write this much).
I believe 'talent' comes down to three things:
- Recognising the way in which you learn most efficiently
- Recognising what it is you want to achieve and how to get there
- Actively attempting to reach that goal
Imagine you have two children and give them each a box of lego.
Now imagine one child takes the box and builds the spaceship pictured on the front. They take great joy in seeing something exciting and intricate and making it for themselves-- it is a great achievement to replicate the picture so perfectly, and very satisfying.
Beside that child, the other one isn't paying attention to the picture on the box at all. This one is building something else-- and you don't really know what it is until they're finished. Turns out it's some kind of melted parrot. Good job kid.
What happened here was that both of these children were given the same tools, guidelines and time, and both pursued an activity they, personally, found to be most enjoyable. They took different approaches and achieved different results, and both are excellent in their own way. The first child may grow up and go to school and find they do very well at maths, science, and other factual tests, because they take great satisfaction in replicating what they know to be correct and can do it superbly. The second child may grow up to be terrible at maths, science, and factual tests, but excel in writing or dance because their passion lies in creating facts for themselves, not replicating what already exists. They don't have time for facts!
Now lets imagine these children grow up and both decide they want to be artists. Great! One takes photographs and redraws them, the other starts painting melted parrots. Both of them carry on in this vein for years, dabbling in what they find fun, growing into young adults who are known as the 'artists of the family', and both of them sticking to exactly what they enjoy and what they're praised for-- replicating what exists, and creating something new.
Eventually the two of them reach a point where they can't seem to get any better. They both stall, unsure of how to go forward. The problem is that they two of them are too much of one thing alone. One is technically gifted, but not creative; they can draw anything you ask them too, but they cannot design. The other is creative, but not technical; they can't copy anything at all, but they can create you anything you suggest, in their own way.
Now lets say the two of them see each others work. What do they say?
'Wow! You're so talented! I could never do that!'
The truth is, they could. They could do exactly what the other has done, but they haven't because it simply never interested them. It's very easy to excel in something when you enjoy it--- gaming, dancing, carving, singing-- but there will always come a point where you need to recognise that if you want to take whatever it is you do to the next level, you need to start working on things you don't enjoy.
These things can be anything at all, as well as things you never knew existed. Something as simple as learning how to draw lines smoothly, or colour light a certain way, or even buying yourself a new tablet because the one you have is old and manky. This is crucial, and the same as buying yourself a bigger lego set; you're making an investment (time and/or money) to provide yourself with more tools to play with.
Lets say the two children, now adults, are working in small jobs alongside other creative people-- some just like them, others not. They are exposed to so many things-- concepts, approaches, processes, tips, tricks, examples, demonstrations, discussions, and opportunities to play-- and upon seeing each of these they feel a flare of something tremendous. A 'YES! I can USE this!' feeling that makes them all squirmy inside. And with, that they scurry away and get back to work on what they love, constantly poking and prodding their creation into shape.
So, to (finally) answer your question, I do believe talent exists, but I believe it only exists because people are able to recognise what they excel in, recognise what they must do to be better, and actually invest the time and effort into achieving it.
Some people learn how to complete these steps at a very early age-- like it's second nature. They are a prodigy, or a 'natural talent', and it's purely because they see what they are doing, see what they must do, and do it. It's as simple as 1, 2, 3. And I know this is a very simplified version of things. Some people face difficulties, some don't have the time. Some aren't exposed to anything new, and some people's dreams are squashed before they've had a chance to form.
The point is, you can do it. Anyone can. You just need to identify what it is you want and go get it.
So go get it!
