Leading life like a marathon

Life is like a marathon
We been running while the clock is ticking
Every minutes goes by, when the hand goes clockwise
Looking back behind you is a path you have been through
And there is no turning back, to re run this track

How many times we wish to take a break and stop
How many times we witnessed others who collapsed and never wake up
How many times we witnessed others who collapsed but stood up
How many times we wish we can run ahead like the one ahead of us
and how many times we tried to encourage others and allow others to encourage us

When will I see the finish line?
When can I give up and say goodbye?
Will someone take over and complete my run?
Will someone sprinkle me with some water?
I am badly dehydrated...
Where is the finishing line?
When will I ever get to pause and say it's done
I am sick of this run
This life of marathon is no fun running under the scorching sun
Just aim me with a gun, and so it will be all done.
