Dang, 14 and you’re already ready for tech jobs? Gotta give you props on that, when I turned 16 (which was back in the late 90s so I’m not that old myself) the first job I had was working the cash register at McDonalds!
I admire your ambition to work in tech at your age, but I’d be more inclined to recommend a different kind of job for you. At your age you should be working the kind of job that most teenagers do, which is basically customer service at retail establishments, or something that involves physical labor—not that I’m suggesting menial labor, but just something that will involve building up your physical ability so you can start establishing your personal health. Of course that’s probably not what you want to do right now, but the average intern will have 10 further years of age on you (as most interns tend to be college-aged from 18 up to 26) which also gives them more life experience and maturity in general. When you’re as young as 14, few people will give you any respect and even fewer will likely give you anything valuable to do.
And besides, when you’re that young no one will expect you to be a developer, so you might as well take advantage of other jobs that will round you out as a person with other life skills. Think of it this way: you have at least 8 more years before you need to think about seriously getting into tech and getting any kind of respect at that age. So there’s no need for you to jumpstart anything. Just keep learning and building up your portfolio is what I’d recommend.
