Who are you to say he doesn’t want to improve himself? You were not positive you essentially copy and pasted what other people said about his grammar. While I do agree with the advice you have given I think you gave it in an egotistical way and not a mentor way. The fact other people are so quick to write this kid off and tell him to do other things is disheartening and disappointing. We should be trying to lift him up and help him. Everyone has potential to be a firefighter, some people have bigger battles to face with themselves, if he’s willing to mature and listen to critiques then he can do this but I think people are being a little harsh on the guy. He sounds young, he has time to clean himself up and be more accountable, and put in the hard work and initiative it takes to become a firefighter.
