People change. They grow up. They get better. They learn. They mature.
The evidence is in the mirror. Aren’t all these things true of you or have you always been enlightened? Have you always been wise or do you also know what it’s like to be a cause of someone else’s inconvenience or sorrow?
What would your life be like if everyone defined your identity by your last bad choice? Be open as the world has been open to you.
Will everyone change? Of course not. But if the cooperation of every single person was the standard for anything, nothing new would ever be possible.
