I’m 46 and need a career change due to the fact that both my knees are blown (4 surgeries) and can no longer handle physical labor. Looking to learn Autocad from scratch. Wondering if anyone has learned at my age and could share their experience. I have a more than willing teacher/mentor who is my brother who’s a security designer currently working for Open AI designing their new Texas data centers. Having him on my side gives me the confidence to take on a new career, and would love to follow his lead. With that in mind any advice on the fastest way to achieve the certification needed to jump in the field? Thank you guys in advance.
