It's easy to be negative about past mistakes and unhappiness. However, it's much more healing to look at ourselves and our past in light of experience, acceptance, and growth. Our past choices are part of us- they do not define us. It's okay to make mistakes. Learning from our past choices is how we grow. Our past mistakes, frustrations, failures were necessary lessons. Sometimes hard and painful, but necessary. We can learn so much from the choices we make- we just need to be open to allowing ourselves to be kind about them. We need to remember that we all make "mistakes" but that does not mean we are inherently bad people. There is a quote from Maya Angeluo that reminds me about kindness in looking at past choices. it says,
“I did then what I knew how to do. Now that I know better, I do better.”
Your past choices are your past choices. They do not need to weight you down or make you feel heavy. You did what you knew and you can grow from there.
