(EDIT: Bit of a long post. Skip to the third last paragraph for conclusion if you can't be bothered reading it all)
I spent much of my teen years into music. I played quite a bit of bass and was in a series of bands. After a few years of that I moved over to music production (electronic). As much as I try I can see that its clear that I do not have a natural talent or aptitude for music. But I carry on anyway, as I love the hobby and do enjoy what I create even though I can see its never really going to be considered great. My best mate, on the other hand, is pretty much a virtuoso. He was amazing at guitar by the age of about 15, better than many professionals. By this age he was also an excellent drummer and since then he has learnt to play many different instruments and produce music electronically. He far surpasses me, or anyone we know in music ability, and there is a very solid underground music scene where I'm from. Most people I know would dabble in some aspect of music creation and while some may be better at their instrument or whatever, his diversity still stands out.
Now he did study music throughout school, college and uni, whereas I did not (I'm pretty much self taught), so he's bound to be better, but he always had the raw talent and the passion to pursue it. His dad was very musical, and while mine can play a few instruments, he never really did growing up. It does make me wonder how much talent really has to do with passion for the craft. Did he have an innate talent, or did he just have the passion to develop it further and faster than someone like myself.
As a kid I used to draw lots and draw big scenes of stickmen fighting it out in massive battles and stuff. I'm told it was very imaginative, but I can't really remember and I don't think there are any left. I used to write a lot, as well I'm told, but as I got older, video games and going out with friends and stuff got in the way. Growing up, I wanted to be a games designer as I always have lots of big ideas for settings and worlds and plots and etc. I was always a worldbuilder, whether I knew it or not. I studied computer science at uni, and while I got a 2:1, I struggled, and the kids all round me were highly skilled, some having practiced their craft since practically their childhood. I do not feel I have an aptitude for that either, and I know I definitely put the time and effort in there.
Following uni I got into worldbuilding via the subreddit which has lead me back to writing. It feels like a better craft for me than music, art or programming, which do not come naturally. I now think writing is the best way for me express my creativity. Which leads me to my conclusion.
Its not about whether you simply have raw talent or not, or just about putting the effort in. Its somewhere in the middle. Its about finding the method that's right for you to release your creativity, and embracing it, working at it and developing it as much as possible.
My advice is create what you want to create, learn you craft and create it to the best of your ability. Do not aim for it to be a success, or to make lots of money. Just aim for it to be the best creation you can make. Eventually the people who like it will find you. Personally I would rather write something that is remembered after I'm gone, than something that made me a load of money and then was forgotten.
Sorry for rambling there haha, I didn't plan to give you the summery of my lifes artistic endevours, it just happened.
