If you want to be the best developer you can be, you're probably better off practicing empathy and communication than tdd or katas. Tech fads fade; being nice and understanding is always in fashion.
If you don't have any role models in your current job or you are just not getting any value, it's a good time to make a change. After leaving my first (and toxic) job, I found an excellent team to work with. Any change could be painful but it's really worth it #DevDiscuss
