I felt completely stuck in my job and returned to school to do CS and now work as a software engineer. It’s never too late, I was in my 30s. If you choose to pursue it do it for the right reasons. Sit down and start to learn a bit of code if you don’t already know how to do some basic stuff. It’s not for everyone that’s for sure. If you have any questions about school as an adult I would be happy to answer. The other poster who said “it’s more about producing good work” is exactly right. good luck
