At some point in high school, I just accepted that some subjects weren’t for me and instead tried to focus on the stuff I was good at. For me, that was mostly chemistry - I was completely lost in that class, and even years after graduating high school, it still bothers me that I didn’t know what was going on. I always told myself I’d go back and relearn everything I either didn’t understand, or did and just forgot - but life got in the way.
