You can’t change your past, you can’t remove your memories either, that’s not the way your mind works but everybody can improve their future.
Who you are today was determined by who you were yesterday.
Your world revolves around the perception you have of yourself. If you beat yourself up over decisions or events from your past, your future will never change.
Only when you learn to accept everything was meant to happen exactly the way it happened will you be in a position to change your future.
If you don’t learn to like who you are today, you will not like who you will become tomorrow.
“Every saint has a past and every sinner has a future.” ~Oscar Wilde
