Years roll by pretty quickly and before you know it, you have aged. Where did time go, you ask? This is one way of looking at where you are in your life.
A better approach is to turn your attention to today and focus on what can you do in the present. A today well-lived makes yesterday a good dream, and tomorrow full of hope and confidence.
You can learn from yesterday, and plan for and anticipate the future. However, action can only be carried out now!
