I’m trying to learn basic culinary fundamentals and I feel really overwhelmed

Hi everyone,
I’m currently trying to learn basic culinary fundamentals on my own, but I honestly feel really overwhelmed.
I didn’t go to culinary school, so I’m not sure if I’m focusing on the right things. I keep seeing topics like French terms, mother sauces, stocks, etc., and I don’t know what I should prioritize.
For those with experience:
What should I REALLY focus on as a beginner?
What topics are the most important to understand first?
Any tips for learning or studying more efficiently?
Any advice would really help me a lot 🙏
