No one can tell what will happen tomorrow
For life is a journey of joy and sorrow

Where no one gets to sleep on the roses
Where no one sees what life really posses

Because every moment that is due to come
carries in it the mysterious sum

Where things are both good and bad
And things are all painful and glad

Comes in and knocks at your door
Because that's why in your life is store

And that's why no one can forsees tomorrow
For life is a mystery has both joys and sorrow.
