Worrying about the past does not change anything.
All it does is cause stress and anxiety.
Stress and anxiety that’s unnecessary, as it’s already done, and there’s nothing you can do that can change it.
What’s happened has happened.
Learn from the past, because that is all you can do.
Let bygones be bygones.
Focus on what you can do, rather than what’s already happened.
That’s how you will make progress, and move forward.
