Travel. If you have the means, do it. I was quite like you. I got interested in history when I was 8. But I couldn't do much with my passion because I'm limited. I live in the third world, struggling middle class, thank fuck for the internet at least. I have no means to exhaust. Then time went on. I'm now 25 who can tell everything about certain topics but for sure may not get to places to reimagine the events nor pay respect to it. You're 14. In a few years time you would have to question when is something just a hobby and what should be your career. Go out there. See as much as you can. That's all there is to it. Then tell the story.
