Do you realize you cannot hold onto any moment? Why? As soon as you know it is here it will be gone. What you can do, though, is to live each moment fully so its value will always be with you.
Understand the more fully and authentically you live each moment, the more your life will be filled with value that you cannot lose. Why? You are able to use it in the moments that soon follow.
Beginning today the value you gain was not the result of any particular moment. It came to you because you opened yourself up to discover that value and begin making it part of your life.
