Learning from experiences is one of the ways in which we decide to cultivate more of what we like about ourselves as opposed to just randomly accepting every way in which we react.
Your habits, priorities, ways in which you interact with people and work that you love, even how your perception is being shaped… All of this partially came from learning from your experiences. We are sum of our experiences, hence they are priceless. What you and I are today is due to what we have experienced and how we decided to label that.
