The past, oh how wonderful it was. If only we could go back to those days. I hear it many times. If we really dig into it, it wasn't really that good. It is just that we know for a fact what has happened. It becomes a comfort zone, a security blanket so to say.
We don't know what the future holds so we become frightened. All kinds of what ifs step in and, usually are quite negative. We visualize and dwell on everything that could go wrong.
How about a different approach: The rest of my life is in front of me. Yes I did many things in the past, some good and some not so good. I need to learn from them and then, excitedly move forward into the future making what could be a reality.
Living in the past is the same old same old over and over. Living for the future will provide more positive experiences than we can possibly imagine.
