You are where you are. You cannot go back to your past and change how you grew. Accept the truth—what’s done is done. The only thing you can do now is start relearning everything in the present. When you relearn and regrow, your past will begin to show up less.
How to relearn? That’s the important question. First, understand what a child develops—habits. Habits eventually become character, and character shapes personality. Our personalities are often unpolished because we developed poor habits, mostly unconsciously. So start with your habits. Build a routine—and stick to it.
