Hi!
You are not too late to be a NM at all. But you have to know that it will take some effort and time. You have to develop your chess skills in an effective way. I wrote a bit on the subject, you could check it out on my post: https://www.chess.com/blog/maafernan/chess-skills-development
Good luck!
I learnt chess when i was 6y\o, then stopped till i was 11y/0o then after a few months i started again. I want to acheive NM atleast before i go to uni as it is for my CV. Thank u
Continue playing chess.
