The present moment is the point of a pen that you draw everything in your life. Some people try chasing future success and they ignore to live in their life clock. On the other hand, some people think about their past and they ignore to notice the important matter of life.
Every minute of your present time is like a little dot which is drew from the past to specific future. If you foolishly focus on something about your past, you will not create something in your present and future moment. Also, if you try chasing your future, you will ignore to proceed in your present moment.
