Place your hand on your chest. Feel the beating of your heart.
It is a reminder that we only have a given amount of heartbeats on this earth. Every beat is a count down.
Use them wisely. Do not let vain distractions get in the way of what is truly important. For our time here is short and temporary, that is how it was determined to become. Each of us are not even sure if we reach the day of tomorrow, or the next hour.
