I wish is a situational song, a story that talks about the regrets that build up in a person's heart when a person does something wrong, realizes it and feels bad about it. We all make Mistakes sometimes and it's ok to feel bad when we do. However what's more Important is that you go right your wrongs if you can And if the mistake you made is irreversible. you have a responsibility not to live in regret and guilt but to share your lessons and experience with others You have to teach them from your wealth of experience so they don't make the same Mistakes you made.
