It is easy to get stuck in the past. To focus on all of the things that went wrong . However there are some very good reasons to keep your self looking ahead.
1- You cannot walk forward while you are staring behind you! Try it sometime.
2- Scars from the past just prove that you made it through the battle.
3- When you focus on the past , you are robbing yourself of what is ahead.
4- Never stumble over the past when you are trying to build your future.
5- Looking at your past failures while trying to build a successful future is double minded thinking. A double minded person is unstable in all of their ways.
Make today the first day of the rest of your life and let the past go.
