Any subject will eventually get complicated once you deep dive into it. The most recent subject I started exploring was coffee. Its pretty basic to make a cup of coffee. But if you go and explore the subject: the types of brewing, the variety of espresso machine models, grinders, recipes, bean origin, roasting, flavour, acidity, etc, you realise that even the most basic thing can become overwhelmingly complicated.
Somehow I ended up chickening out whenever I wanted to start something. I am hoping to look back at this someday and say "Man, I was so stupid".
Dunning-Kruger effect
"Prostul nu stie ca e prost" - is a romanian saying that roughly translates to "The stupid doesn't know (s)he's stupid". This subject has actually been researched and it's called the "Dunning-Kruger effect". You can read more about it here, but the gist of it is in the following picture:
I might be on mount stupid. Or you might be on it. Nevertheless, enjoy the ride.
