Why it doesn't pay to frown

Echoes of good times and bad,
Thoughts beautiful and disturbing,
Visages of people that fade in and out,
Memories that plunge you into pensive reflections,
Life is filled with all of these and many more.
All that I am certain of is my existence this very moment
Everyone has their share of burdens to carry
And bitter battles to fight,
Every breath I take in shouts out
That all that matters is how I feel in this precious moment,
Why then should I weigh down this moment with sorrow?
Every moment that passes by is lost forever,
It is a sin to not live it with a smile on your lips,
Joy in your heart and a skip in your step.
