Looking for any advice. Thanks.
If you play video games, write a mod/cheat for them, or even server host if the game you play allows for it. I am NOT saying to use the cheat to win, but the knowledge you gain from writing one is invaluable if you find it interesting, and the same applies for modding/server hosting. Having played a ton of video games in high school, especially counter strike, I knew a ton of people that hosted servers and wrote cheats, and I personally think it's the best pipeline to being cracked at cs, specifically my friends that developed cheats. If you have an interest in ML, train a model to make market predictions. None of these projects need to be fully flushed out, but its a good conversation piece and employers like seeing self-driven development. You only get less free time the older you get, so get started early! Also enjoy high school, don't let your work consume you.
Also a good time to establish physical health habits. Better shape/good cardio/good diet = more energy.
