About the child prodigies, you can talk about their technique and say that they have better technique than you. But you can`t compare artists just by looking at their techniques. Having an amazing technique does not make you an artist just by itself. For me I know that I need to learn, think, question and analyse everything about art, society, nature and many more if I want to become the artist I set out to be. Yes those prodigies may have better technique than you, but you may have the same and even better technique by working as hard as they did. After that you may put something unique in your art that will distinguish you from everyone else. And that can be the reason why someone will hire you in the future. You can say that it is extremeley difficult but you can`t say that it is impossible. As I said, for me I have to constantly read, think, learn and question as well as improve my technique on drawing and painting to be able have that unique touch.
I understand your concerns as I was having the same ones when I was 18 and it took me 8 years to overcome them. (you can check this thread the answers I got really helped me :
And to be honest I still have doubts about my future from time to time when I think about finding jobs in the future if I can become the concept artist I set out to be. However, for the last few months, I realized that if I don`t at least try to become an artist, it will always make me regret that I have not tried. I now know that I should work for many years doing nothing but drawing and painting even if can`t find any job as a concept artist in the future. Yes I would die to work professionally as an artist but the thing I desire the most is to become an artist first. Don`t let any kinds of concerns stop you from becoming an artist because you may regret it in the future if you give up now.
