C++ is the third programming language I ever tried to learn, I got bored and gave up on both Python and JavaScript after like a month, I now have 150 active hours of learning (I tracked) in C++, and I love it, somehow I find it mentally more stimulating, not sure why.

4th, after basic, assembly & pascal. For a long, long time; it was my default language for personal projects.

But just keeping track of all the features and the exotic ways they interact is a full time job. There are people who have dedicated entire lives to understanding even a tiny corner of the language, and they still don't manage.

Not worth the effort for me, there are other languages.
