Career change, how as it for you?

Hey all!

I’m currently doing the front-end engineer career path here on codecademy and so far I’m really enjoying. Finding kinda difficult but I always liked code. I’m a designer and I’m trying to change to a dev career but I’m feeling kinda nervous because I’m 34y and no experience at all in this area, and I’m not sure how much difficult it will be, but I really need to change career and establish a path for my life!
So, want to ask: how many of you did a codecademy career path and started working in that area? How difficult was it? Did you do any other courses besides codecademy? Which ones do you recommend?
