First. Don't read too many of other people's opinions. Or I better say, follow your own path!

I knew a guy in late 90' who worked in a factory floor. He started tinkering with computers trying to fix them, install software. He had no idea what he's doing at the beginning. He was 40 years old. In the coming years he became a tech wiz. Moved from factory floor to QA camera assembly and programming and on the side had a computer repair business. He started programming on the side as well and became pretty good at it. Real problem-solver guy. The kind of person you want if you're building something no matter hardware or software or both.

To answer your question: No, it's not to late!
