Turning moments in life

"Every one has two lives and the second starts when he realizes he just has one." - Confucius

We often wait until some turning moment in our life, which makes us to think about our present and our future. During this thinking process many realize that there's so much more that we wanted to do and hoped to accomplish. As result, we choose to adjust our present and re-define our path for the future in order to accomplish what we truly desire. So, instead of waiting until such turning moment, why not begin changing our present today and begin creating new opportunities for achieving our wants and needs sooner rather than later?
