If you cringe when you think about your past mistakes, this may help
Think of a time where you have done something embarrassing or stupid. We all can, its just part of being human. Now think about something someone else did around that same time that was embarrassing. Think about what they did or said. Try to remember every detail about what they did. If you are like me, chances are that ,unless it was humorous or extreme, you may have a hard time remembering a lot of these situations about other people.
Now flip that thinking to yourself. If you can’t remember what they did. They don’t remember what you did. If you beat yourself up for your past mistakes just remember: you are the only one thinking about it so cut yourself some slack. You’re human and making mistakes is part of this thing called life. You don’t have to be embarrassed about times you fell short. Take something away from those instances. Learn from them and move forward. You are still alive, act like it.
To add to this, the fact that you cringe at past happenings shows growth. You are no longer that person anymore. The cringe comes hand in hand with a lesson.
Hopefully this helps someone.
