Here is the thing I believe....everyone enters our life to teach us something we need to learn. The most difficult people in our life teach us the hardest, but most important lessons, the ones we need to learn the most. Other people our in our lives act as our Angels, guarding over and protecting us always, teaching us there is light and love in the world. Strangers we stumble upon and exchange a few sentences with can say he exact words that we need to hear that resonate with us. We also enter the lives of others to teach them lessons as well....I don't think we should ever underestimate our impact on others. None of us are here by accident. What if not a single moment or interaction of our time on this earth was incidental? What would you do differently?
