No it's not. It's never too late. Pick up a book, write your first "Hello World!" program, and go from there. Never feel insecure about your age. Never try to convince yourself you have knowledge you don't. Take it one day at a time and one step at a time. Don't leap ahead. Always move from the known to the unknown. Do what you love. Love what you do. If you love programming, it doesn't matter how old you are, you'll get good at it and be able to deliver value to someone who will pay you. Best of luck!!
