Good luck with your studies!
“[...] but I have convinced myself that I still have the ability to self learn from this course regardless of my age.”
On YouTube, there is a Canadian guy called Steve Kaufman (username “lingosteve”) you might like. He is around the same age as you, I think, and a polyglot, having studied around 15 different languages. He champions the idea that you can learn languages successfully no matter what age you are, and he gives some very good advice on how to do so. He’s studied Mandarin, Japanese, Czech, Romanian, and French, among many others, so he’s certainly knowledgeable on the topic.
