Affiliate Marketing Secrets

Will it be difficult for me later in life if I have such a broad way of looking at life, to the point that I do not specialize in anything? My dream career is to be an artist. I would willingly try any medium; visual, music, literature, video games! But I always thought that to be an artist, you need to have a sincere fascination with the things of the world, and I cannot imagine doing that, if I am not open to any point of view, every walk of life. I would be the type to write about things I’ve never experienced.
But people would tell me, and I am worried myself, that I need to specialize in something or else I wouldn’t really have much value to give to the world. Like if I need to be hired, what would they need in me, that’s so unique or unfounded, to hire me?
Is it really worth it to scale yourself down? I can aim as high as I want and at the same time swear to myself that I would never get disappointed because I realistically accept that it might not come true. I don’t care. I am just happy anyway that THAT is not the only view to life. I guess I can take a day job. I do want to have my own name and be employed based on that. I don’t know. I’m only 16. But in my country, I’m a senior already and going to college next year.
So is it really bad not to specialize in anything? Will I not have a name by not having a niche?
