I've thought about this for the last few months. I'm in my 30's and never really cared about math until the last couple years. I'm discovering that it has become somewhat easier now for me to understand and learn new math. I had the usual engineering calc set and hated it. But now that I actually have some goals associated with it I have been able to make progress. I've been particularly interested in ASR and AI/ML. I was deficient in the math needed for it but now I'm getting up to speed rapidly. I think the key is to have had some in-depth exposure to math earlier in life though.
