Did you take chemistry in high school or college? ๐งโ๐ฌ๐งช I'm sure you thought it was a useless science that won't touch your life or help you in any way... but it's not. When I started studying it actively in 7th grade I learnt to distinguish between metals, primitive natural processes, what materials we use every day but don't even know what they are made of. You may think that this is useless too, but if you are foolish, I think you need to strive more for progress and self-development ๐
