This resonates so much with my upbringing.

When I was a kid learning programming, I would skim through the whole book teaching Python and type the code using as much keywords as I learned each day, just to boast on my parents and my non-programmers peers about the obfuscated mess that came after.

As I grew I started to contribute to other open-source projects and I came across every kind of unmaitanable spaghetti code, so that I just gave up contribuiting on said project, that is when I gained the consciousness about being zealous on keeping the code as simple as possible so that the next person who comes after me to change the code don't have as much trouble understanding the code, even myself when I revisit the code later.

That altruistic mindset about caring how others read your code, you don't acquire easily unless you get experience how your previous peers did feel.
