MinggI've made connections between two seemingly unrelated subjects which helped me learn more about them.
This is going to sound really fucking nerdy and stupid but i dont give a shit. In my junior year of high school, I took a personal finance class and learned very very basic ideas regarding the stock market. And honestly I forgot most of what I learned but my teacher drilled it into our head to diversify investments because if one fails you have the other ones to fall back on and it reduces the overall risk.
A few years prior to this I had one goal in life regarding one sport and my whole life revolved around it. Then I got hurt bad and had to quit and then I had absolutely nothing. No life, no friends, etc. Sort of like if you invested all your money into one investment. It's risky. And when I was learning about stocks I was like well damn you can incorporate this in like your social life. So since then I have tried to diversify my interests and not rely too heavily on one aspect of life or one person.
At this time I was also going into biomedical engineering and I was like, when the fuck will I ever need to know anything I learn in this class? Now that I'm going into finance/accounting saying this concept isn't applicable for the real world would be a lie but ya know...a few years ago i thought I'd never need it.
So like maybe that's a pointless epiphany in terms of school and maybe it didn't help my grades but it was actually a pretty significant life lesson for me and I've been trying to incorporate it in my life since.
