Just Keep Trying
Years ago I was having a philosophical discussion with a work colleague ( Willem Bagchus ) regarding the changes we make in life. His little piece of wisdom that I took away from the conversation went something like this. "We all change. I don't think I would hang out with the person I was 10 years ago. I might even hate the kind of person I was 20 years ago."
We've all sinned. In my belief system, only one person walked the earth who was perfect. Some days we don't do our best, and some days we do better.
Just keep trying.
