Best of luck.

I'm 32 and just started my data science course. I'm so excited and terrified by what seems to be basic calculus and logic for others.

I'm a pentester/security guy with no formal background in anything. I was a waiter until I was 27, but always hacked and coded around a bit since I was a young kid. I've done well for myself professionally in the last 5 years, I'm good at the soft skills and speaking, but I always felt so inadequate compared to the serious engineers who did "serious" degrees. Hence why I want to get a serious degree to talk serious stuff with my ML engineer colleagues.
