I'm trying to figure out the best approach to learning computer science fundamentals. Everyone seems to recommend starting with programming languages like Python or C, tackling data structures, and jumping into tech stacks and projects. But honestly, I feel a bit lost with all of it. I want to understand how everything works without overwhelming myself trying to learn everything all at once.
I'm particularly interested in the foundational topics in computer science—like logic, computation theory, and architecture—beyond just basic math like algebra and calculus. I'm concerned that if I keep chasing various directions, I'll just end up going in circles.
Can anyone provide a structured learning path or resources that might help me get started more effectively?

You're probably overthinking this a bit. I recommend checking out CS50 from Harvard. It's a free course that covers all the fundamental concepts you need without getting too bogged down in specifics. Many people who try to learn theory first often forget to apply it, so try balancing the two by building as you learn!
While I’m no expert, I suggest focusing on a specific niche. Whether it’s web development or data science, finding an area you're passionate about can really help. Start with a role that aligns with your interests—like a junior web dev in a preferred tech stack or starting as a data analyst. It's essential to know what you enjoy and what you don’t.
If you’re really committed to this path, consider some structured resources like OSSU Computer Science or Teach Yourself CS. Remember, computer science is about the theory behind programming. It's not always necessary to master CS theories to be a skilled programmer, but understanding data structures and algorithms is definitely crucial.
So much noise out there can be confusing! If you're looking for fundamentals, why not try out an old-school route? Fire up a Commodore 64 emulator, play around with Mikro Assembler, and dive into some 8-bit assembly programming. It’s a fun way to learn loops and conditionals at a basic level, even if it doesn’t lead to a direct career path.
If you're excited about theoretical foundations, that’s great! Just be cautious—you might be caught in what's called tutorial hell. Sometimes, diving deeper into math won't necessarily help you get out of it. Try to apply what you learn practically as you go along.

I get what you're saying, but not everyone avoids building by focusing on theory. Some people truly benefit from understanding the foundations before diving into projects.
