That's very true. We are shaped by our experiences. The only choice we have in the matter is the choice of our response. Good coming from bad is the logical outcome. Of course we aren't always logical so sometimes the lesson gets repeated. In this manner we gain wisdom and become more virtuous. It is the natural, logical progression. Unfortunately not everyone is logical.Do not think you have gained a virtue unless you have first been tried by its opposite.
St Teresa of Avila
