My worst experience ... and best, was when the company I worked for sent me to teach OOAD to the faculty of the Mathematics and Computer Science department of a University in Pennsylvania. There I was, a guy with no degree teaching a group of PhD's the fundamentals of OOAD. Imposter Syndrome? You bet. Nervous? Yes. My mouth felt like it was filled with cotton, and when I picked up a cup of water on the first day, I had to put it back down because my hands were shaking so badly. I could handle a room full of developers, but for me, this was a whole other league. As it turned out, the professors had a blast, and gave me great reviews, but that first day of a five day class was a doozy. After that, I knew I could handle anything.

Can someone plz tell me that are subjects like OOAD(object oriented analysis and design) or requirements engineering actually useful in real projects and jobs...?

So I recently finished a full stack web development bootcamp and I realized something at the end of it... I suck at and consequently hate Javascript... Any idea on how to change that? Whenever I see a task related to JS my first response is NOPE.

Since I lack proficiency in Object Oriented Analysis and Design and Datastructures and Algorithms and this has caused me many problems at work, I must review these.
You'd think you don't need to know the 'dry theoretical matter' as they say, oh but you do.. I found out first hand at one of my tougher programming jobs where you have to create everything manually.

And now, looking at my entire first and second year of university courses regarding this matter.. the amount I have to study is enormous. Datastructures and algorithms alone: 1000+ page book + 500+ slides.. and that's only fresh man year! Yep.
I could say there's a way around it but.. I don't really think there is. If I keep just knowing the basic programming concepts, I won't get far. I need to dive deeper.

Until I master this material, it will keep haunting me in programming jobs.
