Even if you are very gifted at something, you likely need to put a lot of effort.

Most of us are very good at one or two things. And not so good at other things. Being gifted means that we master this area very quickly, for example we can learn to draw, to paint, to play music, to play sports, to solve mathematical problems, to lead people, to host parties (etc) faster than other people around us. Being gifted may be a blessing - if what we are gifted at is consistent with what we want to do in our lives, and if various areas at which we are gifted form a nice skill set that can be used efficiently. For example, if you are good at sports, a great team player, and also good in managing your own business, you can become a very successful (and wealthy) football player. This is however very rare, if you see such a complete skill set in yourself (or your child), go for it!

But being gifted, especially being partially gifted, may also be a source of the problem. I will explain why. Let's say that you have an exceptional musical ear, you hear all the sounds of music, they create a picture in your mind and you can easily, without any effort, remember the whole score of a piece; each instrument separately and how they come together. But when it comes to the ability to translate what you hear to the conventional music notation, this is a problem. You may have tried to learn it, and it is not as easy as you thought. Additionally, you may be highly skilled at mathematics, and certain things in music notation (even though it is quite mathematical), may seem illogical - for example, the half-tones making certain intervals of a scale or a mode. Or you may just have poor motoric skills, and your ability to learn the technique of a musical instrument may come with significant effort. And here you get frustrated: on one hand the whole symphonies sound perfectly in your head, on the other hand, there is little you can do with them. So you may have dreamt about becoming a great musician, yet you end up doing a completely different job.

They key is to stick to what you want, and put enough effort in developing the missing skills. In most cases, this can be done (i.e. unless you have a specific deficit preventing you from developing the skills). If you are not specially talented in an area can take (according to some sources) even 10,000 hours of practice. That's a lot - if you practise 3 hours a day, this will take you almost 10 years. 

If you still want to achieve it, start early and be persistent. You will likely make it.
