All good things will turn into memories when they passes, and you can not hold it or experience it one more time. This reminds us to cherish every moment in our life.
The moment of present is also the same. You should know how to cherish the precious moments when you are breathing, feeling the life with all your senses.
When you are still able to work. When you are loved by someone, or you have someone to love. When you have a family, relatives and friends beside you.
Let all the days you have been living worth remembering. Do not live a boring life that you have to count every day you live, don’t count the day, make the day counts.
