Good luck! I’m going through a similar journey. I’m in my late thirties and only started software engineering professionally 5 years ago, without a formal CS degree, but with a hobby-level affinity for computers. It seems like you have an intrinsic interest in the subject. I think this is THE key, because you will grow the most by figuring things out in a play-like fashion, this will solidify your understanding and build intuition.

Looking back what has helped me a lot is being surrounded by more experienced engineers that were good at teaching (those are quite rare I discovered later). Other than that, read a lot of code, write a lot of code, and keep reflecting on what areas to further develop. Be kind to yourself, this space is huge and no one’s is an expert in all of it. Burn out is real, especially when struggling alone for too long. One thing that has helped me as well is to realise everything in software engineering has been made by humans. None of it is actually ‘unknown magic’, just keep digging deeper to find out how the thing you’re struggling with works on a more fundamental level. The LLM age has made this so much easier.
