Mistakes are painful, but as time goes by, they become a collection of experiences called LESSONS. You don't have to be perfect, I mean no one is perfect, so being beautiful does not mean you can't make mistakes, but it means learning from your collection of mistakes put together.
The mistake we've made is not meant to destroy us, but there were meant to help us realize our hidden potential and power because most mistakes we make only help us realize we can do better or should have done better.
We are meant to be built from the mistakes we have made in our lives and not make our mistakes destroy ourselves. Life is a book and as such, we are supposed to be learning how to do better in every new chapter better than in our previous chapter.
Most times, we don't always know much of what we have in us until we have to dig in a lite, and most times, making mistakes helps us to dig in. So making mistakes isn't a sin but not being able to learn lessons from those collections of mistakes we have becomes an error.
Mistakes are part of life and nobody can live without making mistakes but we can do more and be happy when we learn from our mistakes and not dwell on our mistakes.
