About to start my first job in tech without a degree. Any advice?

I am a 32 year old community college drop out. I worked a lot of odd jobs in my early twenties. My last job I was a BJJ coach and manged other instructors for the gym. After a few years of this I decided I wanted to do something different with my life. So in the past year I learned Python, Linux, Docker, SQL, and got an AWS SAA certification. I recently landed a job with a title “Site Reliability Engineer/Application Support Tier III”

Since this is my first “real” job I would love some advice/recommendations. Anything from “I wish I would have known this at my first job” to just general generic advice would be appreciated.
