The Past

What do you do with past? The good the bad and the ugly. Is it necessary to look at the past? How much should one look at the past. Why look at the past? I have some opinions on the matter and I will try to briefly lay them out here. I am of the opinion one should use the past as a vehicle or mode of transportation to find healing. Try to find a few things, surely you can find one, that were good. Thank whoever for doing good. Sometimes we put so much emphasis on the bad we can't find the good. I have found the past to be very enlightning. It has helped me realize who I am and why I react the way I do. Knowing these facts has helped me work through the issue. What are your feelings?
