Change another person into 'a good one'

When I was in my junior high school year, I used to have a journal. The journal was possessed by myself with my other three friends. One day, one of them (call her A) found it in her house. She shared reading the journal with my other friend (one of them too, call her B). They laughed a lot. When I met A a week ago in Bandung, she told me about my writing on the journal. It was about changing another person into what I called 'a good one'. Then, we both shared our thoughts about that thing.

Hmm.. interesting. I mean it's not a simple thing to do. Sometimes, when I met a person (a friend, family, or else), when I felt he/she was not 'a good person' in my own definition, I wanted to change him/her into the person I wanted him/her to be. I wanted to do it without thinking further. But now, I think when you want to change someone else into 'a good one', you have to ask yourself if you are 'a good person' in your own definition. I realize that I haven't reached my own standard (that 'good person' definition). If I haven't reached that standard yet, how can I change others into that standard of mine? Beside, my standard (that of course is based on my principle) can be not appropriate with another person's standard/principles. If that happens, how rude am I if I force another person to change into 'a good person' in my own version?

Actually, what i'm trying to tell you guys is that you have to stand in front of a mirror. You have to know yourself and realize if you have reached your own standard in being 'a good person' or not. Hope this writing will give you a reason to consider yourself if you are the person who match your own standard or not.
