I'm 37 and just started my new career after many years of doing computers and programming more or less as a hobby with the odd professional part here and there. I worked in physical security for most of the years after school and I feel like I have wasted a lot of time. In 2020 I decided to take some time to go to school again and ended up taking QA for three semesters. I now work as a developer, QA and part-time project manager. Hopefully I will have a long career in front of me but I fear all the time that it's too late. 23 is a good age to start out, and you had some fun in your teens. You'll be fine.
